This paper presents the design of multifunction
monolithic microwave integrated circuits (MMIC) to be
used in transmit/receive modules for onboard satellite
applications. Two chips have been developed: one for
frequency generation including a negatron VCO, a
frequency tripler and a digital frequency divider, and a
second for signal amplification and conversion including
AGC amplifiers and mixers.
The goal of the work is to reduce the number and size
(and consequently the cost) of the circuitry actually in use,
without sacrificing system performance, through the use
of a mature GaAs PHEMT technology. Issues such as
suitable circuit topologies, dc power consumption, circuit
area minimization and optimization are all important
factors addressed during the project.
