2300 MHz to 2900 MHz Balanced Mixer, LO Buffer and RF Balun ADL5363 FEATURES APPLICATIONS Cellular base station receivers Transmit observation receivers Radio link downconverters GENERAL DESCRIPTION The ADL5363 uses a highly linear, doubly balanced passive mixer core along with integrated RF and local oscillator (LO) balancing circuitry to allow for single-ended operation. The ADL5363 incorporates an RF balun to provide optimal performance over a 2300 MHz to 2900 MHz input frequency range. The balanced passive mixer arrangement provides good LO-to-RF leakage, typically better than −30 dBm, and excellent intermodulation performance. The balanced mixer core also provides extremely high input linearity, allowing the device to be used in demanding cellular applications where in-band blocking signals might otherwise result in the degradation of dynamic performance.

The ADL5363 provides two switched LO paths that can be used in TDD applications where it is desirable to rapidly switch between two local oscillators. LO current can be externally set using a resistor to minimize dc current commensurate with the desired level of performance. For low voltage applications, the ADL5363 is capable of operation at voltages down to 3.3 V with substantially reduced current. For low voltage operation, an additional logic pin is provided to power down (<200 μA) the circuit when desired. The ADL5363 is fabricated using a BiCMOS high performance IC process. The device is available in a 5 mm × 5 mm, 20-lead LFCSP and operates over a −40°C to +85°C temperature range. An evaluation board is also available. Table 1.

The combination of design, process, and packaging technology allows the functions of these subsystems to be integrated into a single die, using mature packaging and interconnection technologies to provide a high performance, low cost design with excellent electrical, mechanical, and thermal properties. In addition, the need for external components is minimized, optimizing cost and size. RF SUBSYSTEM The single-ended, 50 Ω RF input is internally transformed to a balanced signal using a low loss (<1 dB) unbalanced-to-balanced (balun) transformer. This transformer is made possible by an extremely low loss metal stack, which provides both excellent balance and dc isolation for the RF port. Although the port can be dc connected, it is recommended that a blocking capacitor be used to avoid running excessive dc current through the part. The RF balun can easily support an RF input frequency range of 2300 MHz to 2900 MHz. The RF subsystem consists of an integrated, low loss RF balun, passive MOSFET mixer, sum termination network. The LO subsystem consists of an SPDT-terminated FET switch and a three-stage limiting LO amplifier. The purpose of the LO subsystem is to provide a large, fixed amplitude, balanced signal to drive the mixer independent of the level of the LO input. A block diagram of the device is shown in Figure 48. VCMI IFOP IFON PWDN COMM 20 19 18 17 16 ADL5363 VPMX 1 15 LOI2 RFIN 2 14 VPSW RFCT 3 13 VGS1 COMM 4 12 VGS0 COMM 5 11 LOI1 6 7 8 9 10 VLO3 LGM3 VLO2 LOSW NC NC = NO CONNECT As the mixer is inherently broadband and bidirectional, it is necessary to properly terminate all the idler (M × N product) frequencies generated by the mixing process. Terminating the mixer avoids the generation of unwanted intermodulation products and reduces the level of unwanted signals at the IF output. This termination is accomplished by the addition of a sum network between the IF output and the mixer. The IP3 performance can be optimized by adjusting the supply current with an external resistor. Figure 37 and 38 illustrate how the bias resistor affects the performance with a 5 V supply. Additionally, dc current can be saved by increasing either or both resistors. It is permissible to reduce the dc supply voltage to as low as 3.3 V, further reducing the dissipated power of the part. (Note that no performance enhancement is obtained by reducing the value of these resistors and excessive dc power dissipation may result.) 09914-051 BIAS GENERATOR The resulting balanced RF signal is applied to a passive mixer that commutates the RF input with the output of the LO subsystem. The passive mixer is essentially a balanced, low loss switch that adds minimum noise to the frequency translation. The only noise contribution from the mixer is due to the resistive loss of the switches, which is in the order of a few ohms. Figure 48. Simplified Schematic Rev. 0 | Page 17 of 24 ADL5363 LO SUBSYSTEM The ADL5363 has two LO inputs permitting multiple synthesizers to be rapidly switched with extremely short switching times (<40 ns) for frequency agile applications. The two inputs are applied to a high isolation SPDT switch that provides a constant input impedance, regardless of whether the port is selected, to avoid pulling the LO sources. This multiple section switch also ensures high isolation to the off input, minimizing any leakage from the unwanted LO input that may result in undesired IF responses. The single-ended LO input is converted to a fixed amplitude differential signal using a multistage, limiting LO amplifier. This results in consistent performance over a range of LO input power. Optimum performance is achieved from −6 dBm to +10 dBm, but the circuit continues to function at considerably lower levels of LO input power. The performance of this amplifier is critical in achieving a high intercept passive mixer without degrading the noise floor of the system. This is a critical requirement in an interferer rich environment, such as cellular infrastructure, where blocking interferers can limit mixer performance. The bandwidth of the intermodulation performance is somewhat influenced by the current in the LO amplifier chain. For dc current sensitive applications, it is permissible to reduce the current in the LO amplifier by raising the value of the external bias control resistor. For dc current critical applications, the LO chain can operate with a supply voltage as low as 3.3 V, resulting in substantial dc power savings. In addition, when operating with supply voltages below 3.6 V, the ADL5363 has a power-down mode that permits the dc current to drop to <200 μA. All of the logic inputs are designed to work with any logic family that provides a Logic 0 input level of less than 0.4 V and a Logic 1 input level that exceeds 1.4 V. All logic inputs are high impedance up to Logic 1 levels of 3.3 V. At levels exceeding 3.3 V, protection circuitry permits operation up to 5.5 V, although a small bias current is drawn. All pins, including the RF pins, are ESD protected and have been tested up to a level of 1500 V HBM and 1250 V CDM. Rev. 0 | Page 18 of 24 ADL5363 APPLICATIONS INFORMATION BASIC CONNECTIONS BIAS RESISTOR SELECTION The ADL5363 mixer is designed to downconvert radio frequencies (RF) primarily between 2300 MHz and 2900 MHz to lower intermediate frequencies (IF) between 30 MHz and 450 MHz. Figure 49 depicts the basic connections of the mixer. To prevent nonzero dc voltages from damaging the RF balun or LO input circuit, ac-couple the RF and LO input ports. The RFIN matching network consists of a series 1.5 pF capacitor and a shunt 12 nH inductor to provide the optimized RF input return loss for the desired frequency band. An external resistor, RBIAS LO, is used to adjust the bias current of the integrated amplifiers at the LO terminals. It is necessary to have a sufficient amount of current to bias the internal LO amplifier to optimize dc current vs. optimum IIP3 performance. Figure 37 and Figure 38 provide the reference for the bias resistor selection when lower power consumption is considered at the expense of conversion gain and IP3 performance. MIXER VGS CONTROL DAC The ADL5363 features two logic control pins, VGS0 (Pin 12) and VGS1 (Pin 13), that allow programmability for internal gate-tosource voltages for optimizing mixer performance over desired frequency bands. The evaluation board defaults both VGS0 and VGS1 to ground. IF PORT The real part of the output impedance is approximately 50 Ω, as seen in Figure 26, which matches many commonly used SAW filters without the need for a transformer. This results in a voltage conversion loss that is approximately the same as the power conversion loss, as shown in Table 3.

Nominal supply decoupling consists of a 10 μF capacitor to ground in parallel with a 10 pF capacitor to ground positioned as close to the device as possible. RF Input Interface. The input channels are ac-coupled through C1. C4 and C5 provide bypassing for the center taps of the RF input baluns. IF Output Interface. T1 is a 1:1 impedance transformer used to provide a single-ended IF output interface. Remove R1 for balanced output operation. C24 and C25 are used to block the dc bias at the IF ports. LO Interface. C10 and C12 provide ac coupling for the LO1_IN and LO2_IN local oscillator inputs. LOSEL selects the appropriate LO input for both mixer cores. R4 provides a pull-down to ensure that LO1_IN is enabled when the LOSEL test point is logic low. LO2_IN is enabled when LOSEL is pulled to logic high. PWDN Interface. R21 pulls the PWDN logic low and enables the device. The PWR_UP test point allows the PWDN interface to be exercised using the an external logic generator. Grounding the PWDN pin for nominal operation is allowed. Using the PWDN pin when supply voltages exceed 3.3 V is not allowed. Bias Control. R22 and R23 form a voltage divider to provide 3 V for logic control, bypassed to ground through C22. VGS0 and VGS1 jumpers provide programmability at the VGS0 and VGS1 pins. It is recommended to pull these two pins to ground for nominal operation. R9 sets the bias point for the internal LO buffers.
