Abstract

In this paper, we present a fully monolithic and compact direct conversion receiver for C-band wireless applications. The receiver occupies a 53×35 mil² die area and dissipates 60 mW of DC power. Utilizing even-harmonic mixing, we demonstrate excellent intermodulation suppression with both 2^nd and 3^rd order intercept points of 14 dBm. This design provides a voltage conversion gain of 6 dB while keeping the DC offsets below -100 dBm for excellent input sensitivity The chip was fabricated with the TriQuint TQTRx GaAs MESFET process
