The AMMC-5040 is a high gain broadband amplifier designed for both military applications and commercial communication systems. This four-stage amplifier has input and output matching circuitry for use in 50 ohm environments. It is fabricated using PHEMT integrated circuit structures that provide exceptional broadband performance. The backside of this chip is both RF and DC ground. This simplifies the assembly process and reduces assembly related performance variations and costs. For improved reliability and moisture protection, the die is passivated at the active areas. This MMIC is a cost effective alternative to hybrid (discrete-FET) amplifiers that require complex tuning and assembly process.
