Abstract :
The design and performance of an X-band amplifier with greater than 3-W CW output power over a 4.5-GHz bandwidth is described. This fully-monolithic amplifier achieved an average power-added efficiency of 18% over the band with 8- to 13-dB gain (2-dB compressed). The two-stage amplifier is fabricated with conventional ion-implanted MESFETs and offers an attractive combination of output power, efficiency, bandwidth and size. This intermediate-bandwidth amplifier is the first of its type to provide greater than 3-W CW output power over the entire X-band.<>
