Distributed amplifiers operate to 40 GHz with positive gain slope

February 16, 2017 // By Jean-Pierre Joosting
Custom MMIC has added two unique distributed amplifiers to their performance leading standard product line – the CMD242 distributed amplifier and the CMD244 distributed driver amplifier.

The CMD242 distributed amplifier features ultra-wideband performance from DC to 40 GHz while delivering 10.5 dB of gain with a flatness of ±1 dB. The noise figure of the amplifier is 4.4 dB, with an output P1dB of 18 dBm and OIP3 of 27 dBm at 20 GHz. With a low current consumption of 100 mA, the CMD242 leads the market for the broad frequency and high dynamic range requirements.

The CMD244 distributed driver amplifier covers DC to 24 GHz, with a unique positive gain slope over frequency range. The positive gain slope feature decreases the requirement for equalizer circuitry, saving SWaP in many communications and measurement designs. The GaAs MMIC has a P1dB of 25 dBm, OIP3 of 32 dBm, 8 dB of gain and a noise figure of 2.5 dB at 10 GHz.
