Abstract :
A highly miniaturized and low power consumption receiver front-end hybrid IC(HIC) including input matching circuits for 880 MHz bands using on-chip high-dielectric constant (/spl epsi//sub r/) capacitors has been newly developed. The HIC is composed of a GaAs IC chip and a ceramic substrate with spiral inductors on its surface. The HIC showed conversion gain of 20.2 dB and noise figure of 4.2 dB at supply voltage of 2.7 V and dissipation current of 3.7 mA. The HIC measures only 5.0 mm/spl times/5.0 mm/spl times/1.0 mm.<>
