J /0 0 19-3468; Rev 0; 10/04 High-Linearity, 1700MHz to 2200MHz Upconversion/ Downconversion Mixer with LO Buffer/Switch Features The MAX2039 high-linearity passive upconverter or downconverter mixer is designed to provide 7.3dB NF and a 7.1dB conversion loss for an RF frequency range of 1700MHz to 2200MHz to support UMTS/WCDMA, DCS, and PCS base-station transmitter or receiver applications. The IIP3 is typically +34.5dBm and +33.5dBm for downconversion and upconversion operation, respectively. With an LO frequency range of 1500MHz to 2000MHz, this particular mixer is ideal for low-side LO injection architectures. (For a pin-to-pincompatible mixer meant for high-side LO injection, contact the factory.) ♦ 1700MHz to 2200MHz RF Frequency Range In addition to offering excellent linearity and noise performance, the MAX2039 also yields a high level of component integration. This device includes a double-balanced passive mixer core, a dual-input LO selectable switch, and an LO buffer. On-chip baluns are also integrated to allow for a single-ended RF input for downconversion (or RF output for upconversion), and single-ended LO inputs. The MAX2039 requires a nominal LO drive of 0dBm, and supply current is guaranteed to be below 135mA. The MAX2039 is pin compatible with the MAX2031 815MHz to 995MHz mixer, making this family of passive upconverters and downconverters ideal for applications where a common PC board layout is used for both frequency bands. The MAX2039 is available in a compact 20-pin thin QFN package (5mm x 5mm) with an exposed paddle. Electrical performance is guaranteed over the extended -40°C to +85°C temperature range. ♦ Integrated LO Buffer Applications ♦ 1500MHz to 2000MHz LO Frequency Range ♦ 1900MHz to 2400MHz LO Frequency Range (Contact Factory) ♦ DC to 350MHz IF Frequency Range ♦ 7.1dB Conversion Loss ♦ +34.5dBm Input IP3 (Downconversion) ♦ +24.4dBm Input 1dB Compression Point ♦ 7.3dB Noise Figure ♦ Integrated RF and LO Baluns ♦ Low -3dBm to +3dBm LO Drive ♦ Built-In SPDT LO Switch with 45dB LO1 to LO2 Isolation and 50ns Switching Time ♦ Pin Compatible with the MAX2031 815MHz to 995MHz Mixer ♦ External Current-Setting Resistor Provides Option for Operating Mixer in Reduced-Power/ReducedPerformance Mode ♦ Lead-Free Package Available Ordering Information TEMP RANGE PIN-PACKAGE PKG CODE MAX2039ETP 20 Thin QFN-EP* -40°C to +85°C (5mm x 5mm) bulk T2055-3 MAX2039ETP-T 20 Thin QFN-EP* -40°C to +85°C (5mm x 5mm) T/R T2055-3 20 Thin QFN-EP* (5mm x 5mm) MAX2039ETP+D -40°C to +85°C lead-free bulk T2055-3 20 Thin QFN-EP* (5mm x 5mm) MAX2039ETP+TD -40°C to +85°C lead-free T/R T2055-3 PART UMTS/WCDMA Base Stations DCS1800/PCS1900 EDGE Base Stations cdmaOneTM and cdma2000® Base Stations PHS/PAS Base Stations Predistortion Receivers Fixed Broadband Wireless Access Wireless Local Loop Private Mobile Radio Military Systems Microwave Links Digital and Spread-Spectrum Communication Systems cdmaOne is a trademark of CDMA Development Group. * EP = Exposed paddle. + = Lead free.

Detailed Description The MAX2039 can operate either as a downconverter or an upconverter mixer that provides 7.1dB of conversion loss with a typical 7.3dB noise figure. IIP3 is +33.5dBm for upconversion and +34.5dBm for downconversion. The integrated baluns and matching circuitry allow for 50Ω single-ended interfaces to the RF port and two LO ports. The RF port can be used as an input for downconversion or an output for upconversion. A single-pole, double-throw (SPDT) switch provides 50ns switching time between the two LO inputs with 45dB of LO-to-LO isolation. Furthermore, the integrated LO buffer provides a high drive level to the mixer core, reducing the LO drive required at the MAX2039’s inputs to a range of -3dBm to +3dBm. The IF port incorporates a differential output for downconversion, which is ideal for providing enhanced IIP2 performance. For upconversion, the IF port is a differential input. Specifications are guaranteed over broad frequency ranges to allow for use in UMTS, cdma2000, and 2G/2.5G/3G DCS1800, and PCS1900 base stations. The MAX2039 is specified to operate over an RF frequency range of 1700MHz to 2200MHz, an LO frequency range of 1500MHz to 2000MHz, and an IF frequency range of DC to 350MHz. Operation beyond these ranges is possible; see the Typical Operating Characteristics for additional details. 12 This device can operate in high-side LO injection applications with an extended LO range, but performance degrades as fLO continues to increase. See the Typical Operating Characteristics for measurements taken with fLO up to 2200MHz. For a device with better high-side LO injection performance, contact the factory. RF Port and Balun For using the MAX2039 as a downconverter, the RF input is internally matched to 50Ω, requiring no external matching components. A DC-blocking capacitor is required since the input is internally DC shorted to ground through the on-chip balun. The RF return loss is typically 18dB over the entire 1700MHz to 2200MHz RF frequency range. For upconverter operation, the RF port is a singleended output similarly matched to 50Ω. LO Inputs, Buffer, and Balun The MAX2039 can be used for either high-side or lowside injection applications with a 1500MHz to 2000MHz LO frequency range. For a device with a 1900MHz to 2400MHz LO frequency range, contact the factory. As an added feature, the MAX2039 includes an internal LO SPDT switch that can be used for frequency-hopping applications. The switch selects one of the two singleended LO ports, allowing the external oscillator to settle on a particular frequency before it is switched in. LO switching time is typically less than 50ns, which is more than adequate for virtually all GSM applications. ______________________________________________________________________________________ High-Linearity, 1700MHz to 2200MHz Upconversion/ Downconversion Mixer with LO Buffer/Switch High-Linearity Mixer The core of the MAX2039 is a double-balanced, highperformance passive mixer. Exceptional linearity is provided by the large LO swing from the on-chip LO buffer. Differential IF The MAX2039 mixer has an IF frequency range of DC to 350MHz. Note that these differential ports are ideal for providing enhanced IIP2 performance. Single-ended IF applications require a 1:1 balun to transform the 50Ω differential IF impedance to a 50Ω single-ended system. After the balun, the IF return loss is better than 15dB. The differential IF is used as an input port for upconverter operation. The user can use a differential IF amplifier following the mixer but a DC block is required on both IF pins. In this configuration, the IF+ and IF- pins need to be returned to ground through a high resistance (about 1kΩ). This ground return can also be accomplished by grounding the RF TAP (pin 3) and AC-coupling the IF+ and IF- ports (pins 19 and 18). Applications Information Input and Output Matching The RF and LO inputs are internally matched to 50Ω. No matching components are required. Return loss at the RF port is typically 18dB over the entire input range (1700MHz to 2200MHz) and return loss at the LO ports is typically 16dB (1500MHz to 2000MHz). RF and LO inputs require only DC-blocking capacitors for interfacing. The IF output impedance is 50Ω (differential). For evaluation, an external low-loss 1:1 (impedance ratio) balun Table 1.

Bias Resistor Bias current for the LO buffer is optimized by fine tuning resistor R1. If reduced current is required at the expense of performance, contact the factory for details. If the ±1% bias resistor values are not readily available, substitute standard ±5% values. Layout Considerations A properly designed PC board is an essential part of any RF/microwave circuit. Keep RF signal lines as short as possible to reduce losses, radiation, and inductance. For the best performance, route the ground pin traces directly to the exposed pad under the package. The PC board exposed pad MUST be connected to the ground plane of the PC board. It is suggested that multiple vias be used to connect this pad to the lower-level ground planes. This method provides a good RF/thermal conduction path for the device. Solder the exposed pad on the bottom of the device package to the PC board. The MAX2039 Evaluation Kit can be used as a reference for board layout. Gerber files are available upon request at www.maxim-ic.com. Power-Supply Bypassing Proper voltage-supply bypassing is essential for highfrequency circuit stability. Bypass each VCC pin and TAP with the capacitors shown in the Typical Application Circuit; see Table 1. Place the TAP bypass capacitor to ground within 100 mils of the TAP pin. ______________________________________________________________________________________ 13 MAX2039 If frequency hopping is not employed, set the switch to either of the LO inputs. The switch is controlled by a digital input (LOSEL): logic high selects LO2, logic low selects LO1. In order to avoid damage to the part, voltage MUST be applied to VCC before digital logic is applied to LOSEL (see the Absolute Maximum Ratings). LO1 and LO2 inputs are internally matched to 50Ω, requiring only a 22pF DC-blocking capacitor. A two-stage internal LO buffer allows a wide-input power range for the LO drive. All guaranteed specifications are for an LO signal power from -3dBm to +3dBm. The on-chip low-loss balun, along with an LO buffer, drives the double-balanced mixer. All interfacing and matching components from the LO inputs to the IF outputs are integrated on chip.

It is important that the PC board on which the MAX2039 is mounted be designed to conduct heat from the EP. In addition, provide the EP with a low-inductance path to electrical ground. The EP MUST be soldered to a ground plane on the PC board, either directly or through an array of plated via holes. 14 Chip Information TRANSISTOR COUNT: 1212 PROCESS: SiGe BiCMOS ______________________________________________________________________________________ High-Linearity, 1700MHz to 2200MHz Upconversion/ Downconversion Mixer with LO Buffer/Switch GND IF+ IF- GND GND 20 19 18 17 16 TOP VIEW 15 LO2 2 14 VCC TAP 3 13 GND GND 4 12 GND GND 5 11 LO1 VCC 1 RF MAX2039 Pin Configuration 8 9 VCC LOSEL GND 10 7 LOBIAS VCC 6 MAX2039 ______________________________________________________________________________________ 15 Package Information (The package drawing(s) in this data sheet may not reflect the most current specifications.
