Abstract :
A GaAs MMIC chip-set applicable for various mobile communication systems has been developed. The chip-set consists of (1) low-noise amplifier (LNA) with diversity switching capability and (2) integrated mixer with an amplifier for local oscillator signal. The notable feature of these ICs is the dramatic reduction of pin counts and the improvement of high frequency characteristics due to on-chip ferroelectric bypass capacitors of barium strontium titanium (εr=300). These ICs can be mounted in a small mini-mold package with 6-pin counts
