Abstract :
A monolithic 1 to 50 GHz distributed amplifier has been developed using a MODFET IC process to demonstrate a saturated power in excess of 20 dBm. The power output at the -1 dB gain compression point is greater than 18 dBm across the frequency range. The small signal gain is 8.5 dB+or-0.3 dB, and both input and output return loss are less than -10 dB. Physical layout considerations placed constraints on the design that resulted in a compromise between gain, RF voltage drive, and gain flatness.<>
