Development of MMIC SSPA for 20GHz Band
20GHz 대 MMIC SSPA 개발
Abstract
A 2watts MMIC(Monolithic Microwave Integrated Circuits) SSPA(Solid State Power Amplifiers) for 20GHz band communication systems has been designed, manufactured and measured. The 0.15um pHEMT technologywith the gate size of 400um for single device was used for the fabrication of MMIC Power Amplifier chips. The precision MIC patterns for the peripherals like power combiner/divider and microstrip lines were realized using hard substrate for gold wire/ribbon bonding. The measured data shows that this MMIC SSPA has the linear gain of 18dB, output power of 33.42dBm(2.2Watts)at 20~21GHz.
