GaAs MMICs for use in upconverter module for Ka-band OBS satellite transponders

GaAs MMICs has been developed for use in the upconverter module for on-board switching Ka-band satellite transponders. There are four kinds of MMICs: an S-band medium power amplifier, a K-band medium power amplifier, an S to K-band mixer, and X to Ku-band frequency doubler. The four chips have been...

Description
Summary:GaAs MMICs has been developed for use in the upconverter module for on-board switching Ka-band satellite transponders. There are four kinds of MMICs: an S-band medium power amplifier, a K-band medium power amplifier, an S to K-band mixer, and X to Ku-band frequency doubler. The four chips have been fabricated on a wafer using 0.15 /spl mu/m GaAs p-HEMT technologies. A upconverter module using the MMICs with a function of the frequency conversion from 3 GHz to 20 GHz has been developed and showed the RF performance of the 17.1/spl plusmn/0.2 dB conversion gain, the 0.2 nsp-p group delay, the 46.67 dBc C/IM/sub 3/, and 1.15:1 in/out VSWR.
