摘要

A miniaturized receiver front-end hybrid IC (HIC) using MBBn(microbump bonding) technology has been demonstrated. A GaAs IC die wasndip-chip bonded on a ceramic substrate with matching circuits on itsnsurface. New technologies such as 0.5 Μm gate buried p-layer MESFETs,non-chip high-dielectric constant capacitors, and intermediate tunedncircuits have enabled miniaturization and low power-consumption at thensame time. The fabricated HIC measured only 3.5×4.0×1.0 mmnwhich corresponded to a 64% reduction from the conventional one.nConversion gain of 16.0 dB, IP3 out of 0 dBm, noise figure of 5.1 dB,nand image rejection ratio over 20 dBc were obtained for the new HIC atn1.9 GHz, 3.0 V, and 4.5 mA of power supply
