High Dynamic Range Low Noise Amplifier 800 - 1000 MHz Features • Low Noise Figure: 1.2 dB • High Input: +18 dBm at 8 V, 60 mA bias +6.5 dBm at 3 V, 20 mA bias • High Gain: 15 dB • Single Supply: +3 to +8 VDC • Low Cost SOIC-8 Plastic Package • Adjustable current: 20 to 80 mA with external resistor AM50-0003 V4 Functional Block Diagram GND GND REXT VDD Description M/A-COM’s AM50-0003 is a high dynamic range, GaAs MMIC, low noise amplifier in a low cost, SOIC 8-Lead, surface mount, plastic package. It employs external input matching to obtain optimum noise figure performance and operating frequency flexibility. The AM50-0003 also features flexible biasing to control the current consumption vs. dynamic range trade-off. The AM50-0003 can operate from any supply voltage in the 3V to 8V range. Its current can be controlled over a range of 20 mA to 80 mA with an external resistor. The AM50-0003 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 AMPS, GSM, and ETACS base stations. It is also useful as a gain block, buffer, driver, and IF amplifier in both fixed and portable cellular and 900 MHz ISM systems. The AM50-0003 is fabricated using a low-cost 0.5micron gate length GaAs process. The process features full passivation for increased performance reliability. The AM50-0003 is 100% RF tested to ensure performance specification compliance.
