Description

M/A-COM’s AM50-0004 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 AM50-0004 also features flexible biasing to control the current consumption vs. dynamic range trade-off. The AM50-0004 can operate from any positive supply voltage in the 3 V to 8 V range. Its current can be controlled over a range of 20 mA to 60 mA with an external resistor. The AM50-0004 is ideally suited for use where low noise figure, high gain, high dynamic range, and low power consumption are required. Typical applications included receiver front ends in PDC, DCS-1800, DCS-1900 and other PCN/PCS base stations. It is also useful as a gain block, buffer, driver, and IF amplifier in both fixed or portable PDC and PCN/PCS systems. The AM50-0004 is fabricated using a low-cost 0.5- micron gate length GaAs process. The process features full passivation for increased performance and reliability. The AM50-0004 is 100% RF tested to ensure performance specification compliance. Pin Configuration Pin No. Pin Name Description

Cross Section View The AM50-0004SMB Designer’s Kit allows for immediate evaluation of M/A-COM’s AM50-0004. The Designer’s Kit includes an AM50-0004 mounted on an evaluation board and five loose AM50-0004’s. The evaluation board consists of the recommended external surface mount circui try, RF connectors, and a DC multi-pin connector, all mounted to a multi-layer FR-4 PCB. The AM50-0004SMB evaluation PCB is illustrated below with all functional ports labeled. Designer’s Kit AM50-0004SMB Evaluation PCB & RF Connector Losses Port Reference Approximate RF Loss RF In 0.15 dB @ 1785 MHz RF Out 0.15 dB @ 1785 MHz Recommended PCB Configuration Layout View AM50-0004 Evaluation Board The DC connector on the Designer’s Kit PCB allows convenient DC line access. This is accomplished by one or more of the following methods: A.) A mating female multi-pin connector (Newark Electronics Stock # 46F-4658, not included). B.) Wires soldered to the necessary pins (not included). C.) Clip leads (not included). The PCB dielectric between RF traces and RF ground layers should be chosen to reduce RF discontinuities between 50 Ω lines and package pins. M/A-COM rec- ommends an FR-4 dielectric thickness of 0.008” (0.20 mm) yielding a 50 Ω line width of 0.015” (0.38 mm). The recommended RF metalization thickness is 1 ounce copper.
