Abstract
This paper describes the design and performance of
a -band ampli fier with over 600 W of saturated output power .
This amplifier is intended for use in commercial broadcast satellite
uplink base stations. The ampli fier uses spatial power combining
to combine the output powers of sixteen internally matched 45-W
GaAs FETs. The ampli fier also comprises pre-ampli fication and
driver amplification stages, a level control variable attenuator, and
a predistortion linearizer. The unit also includes a power
