HMC990LP4E v00.0312 MIXERS - SMT BROADBAND HIGH IP3 DUAL CHANNEL DOWNCONVERTER, 0.7 - 3.5 GHz Typical Applications Features The HMC990LP4E is Ideal for: Broadband Operation with no external matching • Multiband/Multi-standard Cellular BTS Diversity Receivers Industry’s Most Compact Solution, 4x4 mm QFN Package • GSM & 3G & LTE/WiMAX/4G • MIMO Infrastructure Receivers • Wideband Radio Receivers • Multiband Basestations & Repeaters High-side and Low-side LO injection Operation Wide IF Frequency Range High Input IP3 of +25.6 dBm @ 2200 MHz Power Conversion Gain of 7 dB Input P1dB of 12 dBm SSB Noise Figure of 9 dB 55 dBc Channel-to-Channel Isolation Dedicated Enable Pins for IF & LO amplifiers Single-ended RF & LO input ports Functional Diagram General Description The HMC990LP4E is a high linearity, dual channel downconverting mixer optimized for multi-standard diversity receiver applications that require low power consumption and small size. The HMC990LP4E features new wideband limiting LO amplifiers to achieve an unprecedented RF bandwidth of 700 MHz to 3500 MHz. Unlike conventional narrow-band downconverter RFICs, the HMC990LP4E supports both high-side and low-side LO injection over the entire RF frequency band. The RF and LO input ports are internally matched to 50 Ω. The HMC990LP4E integrates LO and IF amplifiers with enable functions, LO and RF baluns and high linearity passive mixer cores with bias control interface. The balanced passive mixer combined with high-linearity IF amplifier architecture of HMC990LP4E provides excellent LO-to-RF, LO-to-IF, and RF-to-IF isolations. The HMC990LP4E provides a very low noise figure of 9 dB, and high IIP3 of +25.6 dBm allowing device to be used in demanding wideband applications. The HMC990LP4E’s input IP3 can be further improved by external matching for narrow-band applications. The HMC990LP4E has typical less than 1.5 W power consumption which can be optimized through external bias control pins. The HMC990LP4E also features a very fast enable control interface to be used for power saving in Time Division Duplex (TDD) applications. The HMC990LP4E is housed in a RoHS compliant 4x4 mm leadless QFN package. 1 For price, delivery and to place orders: Hittite Microwave Corporation, 2 Elizabeth Drive, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com Application Support: Phone: 978-250-3343 or [email protected] HMC990LP4E v00.0312 BROADBAND HIGH IP3 DUAL CHANNEL DOWNCONVERTER, 0.7 - 3.5 GHz Electrical Specifications, TA = +25 °C, IF Frequency = 150 MHz, LO Power = 0 dBm, RF=900 MHz [1] RF=1900 MHz [2] RF=2200 MHz [2] RF=2700 MHz [2] Typ.

The HMC990LP4E’s low noise and high linearity performance makes it suitable for a wide range of transmission standards, including TDD, FDD, LTE, CDMA, GSM, MC-GSM, W-CDMA, UMTS, TD-SCDMA, WiMAX applications. The HMC990LP4E offers an easy-to-use and complete frequency conversion solution for diversity and MIMO receiver applications in a highly compact 4x4 mm QFN package. The HMC990LP4E greatly simplifies the design of diversity and MIMO receiver applications by increasing the integration level and reducing the number of required circuit elements thereby reducing cost, area, and power consumption. Principle of Operation MIXERS - SMT Application Information The HMC990LP4E has two identical, symmetrical double-balanced passive mixers. These mixers are driven from a common single-ended LO input that is broadband matched to 50 Ω and requires only a standard DC-blocking capacitor. The single-ended LO input is converted into differential through the on-chip integrated balun followed by a LO driver stage. The differential signal is divided into two differential paths and each mixer is driven by a separate LO amplifier. The HMC990LP4E’s single-ended RF inputs are converted into differential through the on-chip integrated baluns. The single-ended RF inputs are internally broadband matched to 50 Ω and require only standard DC-blocking capacitors. However, the HMC990LP4E’s RF inputs can be externally matched for narrow band application frequency with a simple matching network including a series inductor and a shunt capacitor to further improve the performance. Please refer to the application circuit for narrowband RF input matching for the detailed information. The HMC990LP4E’s IF amplifiers are designed for differential 200 Ω output impedance. A few external components are required at these IF outputs for the broadband frequency response as recommended in the application circuit. Please refer to the IF output interface section for more information. The HMC990LP4E requires 5V and 3.3V supply voltages and external bias voltages. Bias voltages generate reference currents for the IF and LO amplifiers. 3.3V supply voltage and the external bias voltages can be generated from 5V supply voltage to operate with a single supply. Please refer to the single supply operation section for more information. The reference currents to the LO amplifiers and IF amplifiers can be disabled through LO_EN and IFA1_EN, IFA2_EN pins respectively. If the EN pins are connected to LOW or left unconnected, the part operates normally. If the EN pins are connected to HIGH, the LO amplifiers and IF amplifiers are disabled. Single Supply Operation The HMC990LP4E requires 5V and 3.3V supply voltages and the external bias voltages. The external bias voltages except VGATE1, VGATE2 pin voltages are already generated from 5V supply voltage on evaluation board (see application circuit). These bias voltages can be optimized by series resistances with appropriate values from the 5V supply to the bias pins (VCS1, VCS2, LO_BIAS1, LO_BIAS2). The resistor values on VCS1, VCS2 and LO_BIAS1, LO_BIAS2 traces on evaluation board are 590 Ohms and 270 Ohms respectively. Refer to the VCS Interface and LO_BIAS Interface section for more information. The nominal VGATE1, VGATE2 pin voltages are 4.8V that is applied externally. However VGATE1, VGATE2 pin voltages can be tuned between 4.7V and 5V for optimization of Input IP3 and conversion gain performances. After VGATE1, VGATE2 pin voltages are optimized, these pin voltages can be generated from 5V supply by changing the values of series resistors, R14 and R15. Refer to the VGATE interface section for more information.

VDD_LO1 and VDD_LO2 pins are shorted and connected to VDD_LO1 test point on evaluation board, hence a 10 Ohms resistor (Rvdd_lo) can be added in series with VDD_LO1 test point as shown in Figure 1. The resistor must have a power rating of 1/2W or more. Figure 1. Interface to generate 3.3V for VDD_LO1 and VDD_LO2 pins from 5V Supply.
