Marki Microwave ADM1-0026PA Broadband Distributed Amplifier
Marki Microwave ADM1-0026PA Broadband Distributed Amplifier is a complete LO driver solution for use with all Marki mixers up to 26.5GHz. This single-stage packaged GaAs MMIC distributed amplifier integrates all required biasing circuitry. It offers 12dB typical gain and 21dBm saturated output power, which is suitable for driving all L, M, I, and H mixers. In saturation, it produces a square wave that is optimal for driving a T3 with the highest linearity. The amplifier is operated with a +3V to +7V positive bias and an optional current-reducing negative voltage. While optimized as a mixer LO driver, it is suitable for many applications in test and measurement and laboratory applications.
