Abstract

An 800 MHz-band front-end Multi-Chip Module (MCM) was developed for antenna diversity type handset terminals of Japanese personal digital cellular systems (PDC). This module includes a dual input GaAs FET low noise amplifier (LNA) with switching function, a SAW filter and a GaAs dual-gate FET mixer. Since the dual input LNA works as two independent LNAs and a SPDT switch, very small size and low production cost front-end MCM can be obtained. The package size of this MCM is 0.13 cc. With -10 dBm local input power and supplied d.c. current of 4.0 mA and d.c.voltage of 3 V, noise figure of 3.2 dB and conversion gain of 22.5 dB were obtained.
