Abstract
A coplanar millimeter wave doubler MMIC covering the entire G-Band was developed. Based on a 50 nm metamorphic HEMT technology, the circuit demonstrates an output power of more than -12 dBm between 150- and 220 GHz for an input power of 0 dBm. By increasing the input power to 12 dBm an output power exceeding 0 dBm was obtained in the frequency range between 180- and 220 GHz. Good fundamental rejection was ensured by using a Marchand Balun for balancing the design. The doubler was also used to provide the LO signal for a 170 to 200 GHz resistive FET mixer, yielding a conversion loss of 10 dB.
