Abstract

We have designed and fabricated ASK modulator MMIC operating at 5.8GHz for OBE used in AGPS (Automatic Gate Passing System). ASK modulator MMIC was designed to apply a sing1e supply voltage of 3V to the drain in order to decrease ACP (Adjacent Channel Power). The measurement result of this chip exhibits on/off characteristic over 30dB. The design parameters are optimized through ADS simulation tool. The layouts and fabrication o( ASK Modulator MMIC were designed and fabricated by using ETRI 0.5${\mu}{\textrm}{m}$ MESFET library. The chip sizes were 1mm $\times$1mm. The performance analysis of the implemented ASK Modulator based on the design parameters is accomplished.
