AbstractA beam-hopping system utilizing a phased array and solid-state power amplifiers has previously been introduced for application in EHF communications satellites. The performance of a 5-bit P-I-N-diode phase shifter developed for use at 20 to 21-GHz is presented. The development and characterization of 0.5-W K-band GaAs MESFETs is discussed together with their performance capability. The performance of experimental amplifier designs is included.
