42– 68 GHz broad band low noise high gain MMIC amplifier

A V band (42– 68 GHz) MMIC broad band low noise amplifier for 60 GHz high data rate indoor wireless communication system has been designed and tested. The amplifier has been designed in conjunction with other transceiver MMIC in the 0.15 μm GaAs pHEMT process of UMS (PH15). The measurement results matched very well with the simulation ones based on the extensive circuit and EM co-simulations. The compact amplifier, which is only approx. 1.9×1.2 mm
²
with 100pF on- wafer decoupled capacitor, gives out a gain of 22 dB and a noise figure of 3.5dB with 110 mW DC power consuming. It is well matched in the band 42– 68 GHz.
