The ADM1-0026PA is a complete LO driver solution for use with all Marki mixers up to 26.5 GHz. This single-stage packaged GaAs MMIC distributed amplifier integrates all required biasing circuitry. It offers 12 dB typical gain and 21 dBm 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 +7 V 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. 


Electrical Specifications - Specifications guaranteed from -55 to +85°C, measured in a 50-Ohm system.
