A highly integrated MMIC K-band transmit/receive chip

A highly integrated, wideband, monolithic-microwave-integrated-circuit (MMIC) transmit/receive (T/R) chip designed for both commercial and military FM CW applications is discussed. The MMIC circuit was designed using 0.25- mu m pseudomorphic high-electron-mobility-transistor (HEMT) technology. The T/R chip has three three-stage amplifiers, an active power divide, a diode double-balanced mixer and a voltage-controlled oscillator (VCO), all integrated on a single chip 96 mils*71 mils (2.4 mm *1.8 mm) in size.<
