Abstract :
A state of art 6 to 18 GHz power amplifier module, combining two custom designed MMIC power amplifiers, has been fabricated and tested. Measured results show that the module is capable of delivering an output power of 10 W with /spl ges/15 dB gain. A second iteration power amplifier MMIC design is also described with improved output power capability. By power combining 4 of these amplifiers a module, output power in excess of 25 W is expected, thus making Travelling Wave Tube Amplifier (TWTA) replacement a real possibility.
