| Low Noise Amplifier 1.7 - 2.0 GHz Features * * * * * * * Low Noise Figure: 1.65 dB High Gain: 20 dB Low Power Consumption: 3 to 5 V, 8 mA High Dynamic Range DC Decoupled RF Input and Output No External RF Tuning Elements Necessary Low Cost SOIC-8 Plastic Package MAAM12031 V4 Functional Schematic GND 8 VDD 7 RF OUT 6 GND 5 Description M/A-COM's MAAM12031 is a high performance GaAs MMIC low noise amplifier in a low cost SOIC 8-lead surface mount package. The MAAM12031 employs a fully monolithic design which eliminates the need for external tuning networks. It can be biased using 3 or 5 volt supplies and has an option for biasing at higher currents for increased dynamic range. The MAAM12031 is ideally suited for use where low noise figure, high gain, high dynamic range and low power consumption are required. Typical applications include receiver front ends in the Japanese Personal Handy Phone Service (PHS), Private Branch Exchange (PBX) and Personal Communications and Networks (PCS, PCN) markets, as well as standard gain blocks, buffer amps, driver amps and IF amps in both fixed and portable systems. M/A-COM's MAAM12031 is fabricated using a mature 0.5-micron gate length GaAs process. The process features full passivation for increased performance reliability. 1 GND 2 R1 (optional) 3 RF IN 4 GND Pin Configuration Pin No. 1 2 3 4 1. 2.

Pins 1, 4, 5 and 8 must be RF and DC grounded as shown. Pin 3 is the RF input, pin 6 is the RF output. VDD is applied on pin 7. This pin must be bypassed with a 500 pF surface mount MLC capacitor, mounted as close as possible to pin 7, and RF decoupled with a chip inductor having a minimum value of 15 nH (as shown in the Recommended PCB Configuration). Pin 2 allows use of an external resistor to ground for optional, higher current bias. For nominal current operation no resistor is used. For optional 20 mA current operation, connect a 35 to 40 ohm chip resistor (as show in the Recommended PCB Configuration).
