2–4 GHz 50 W and 100 W wideband GaAs transistor power amplifier units

The results of a development and an experimental investigation of 50 Watt and 100 Watt wideband of units of GaAs transistor amplifiers of a range 2 - 4 GHz are presented. The units are based on serial wideband GaAs transistor amplifiers. There have been two units developed. A PM24-C8 times 2 unit consists of two serial wideband amplifiers PM24-C8 with identical gain-frequency and phase difference characteristics and two tandem couplers. The photograph of PM24-C8 times 2 is presented on Fig. 4. A PtVI24-C8 times 4 unit consists of four amplifiers PM24C8 and six tandem couplers. The picture of PM24-C8times4 is presented. The results of measurements of output power in a linear mode and saturation power of units. Modules of resulting parameters are presented. The size of PM24-C8 times 2 unit is 395 times 180 times 155 millimeters and size of PM24-C8 times 4 unit is 395 times 180 times 280 millimeters.
