Abstract :
A single-chip transmitter/receiver MMIC operating from 1.25 to 3 GHz and incorporating most of the RF functions of a modern communication system is presented. The device incorporates: a direct vector modulator with the necessary phase shifter circuits, an output amplifier for the transmitter, a low-noise amplifier and a down-converter with image rejection. The circuit has 60 MESFETs and more than 250 passive components in a 5.0/spl times/2.4 mm chip and has been manufactured using 0.5 micron GaAs MESFET process.<>
