Abstract :
This paper describes the design and performance of new compact and low cost Ka-band power amplifiers. The main features of the power amplifiers are: 27 dBm to 35 dBm minimum output power for -16 dBm input power over the frequency range of 27.5-31 GHz. To reduce losses MIC, MMIC and waveguide technologies are employed in the development and fabrication of this set of power amplifiers. Employing waveguide technology has minimized losses in the power combiner. Three power amplifiers are described in this paper. The first amplifier is a 0.5 W power amplifier, the second is a 1.5 W power amplifier, and the third amplifier is a 3.2 W power amplifier
