Abstract

A linear mixer with cross-coupled common-source, common-gate pair FET´s was proposed and its performances were verified in the GaAs MESFET monolithic transmitter for cellular hand-held phones. The transmitter showed measured conversion gain of 31.2/spl sim/31.6 dB at LO input power of -5/spl sim/0 dBm, 1 dB compression point of power gain was 9.5 dBm at output power, and two-tone (with offset frequency /spl Delta/f=442.5 kHz) third-order intermodulation distortion (IMD3) at a total output power of 0 dBm was to be -47 dBc with a 3 V of supply voltage and 43 mA of current consumption.
