Paper Abstract

Two variable gain MMIC module designs for space applications are described. In the baseline MMIC module which has a maximum gain of 50 dB, with 30 dB of dynamic gain control over 3.7 to 4.2 GHz band, the MMIC chips are mounted in custom using a low-cost ceramic package technology. The custom ceramic package is a hermetic, dual-shielded cavity enclosure with 70 dB measured cavity isolation. The baseline module is considered to be an excellent candidate for insertion into a solid state power amplifier as a predriver circuit. A second module design uses a metal package with a single chip and discrete components mounted within the package and is characterized for application as an ALC circuit. This module has a 20-dB gain with 10 dB dynamic gain control. It is concluded that the insertion of monolithic microwave integrated circuit technology into satellite applications makes it possible to reduce weight, size, and manufacturing time.
