Abstract :
The authors describe the design and performance of a range of MMIC components suitable for satellite systems operating in X- and Ku-band. The chips have all been fabricated with the GEC-Marconi (Caswell) standard F20 foundry process, which provides 0.5 μm gate-length ion-implanted MESFETs, and through-GaAs via-holes. The circuits described are: a small-signal amplifier for use as a front-end gain block, a balanced amplifier suitable for a transmitter predriver chain, a 1 W power amplifier, an analogue phase shifter, a mixer suitable for receivers and up-converters, and finally a VCO suitable for integration into a phase-locked oscillator subsystem
