Abstract :
The authors have developed a W-band monolithic two-stage conductor-backed coplanar waveguide (CBCPW) low-noise amplifier using pseudomorphic AlGaAs/InGaAs/GaAs HEMT devices. The amplifier exhibits a noise figure of 4.2-4.8 dB with an associated gain of 12 dB from 92 to 96 GHz. The circuit was tested using a W-band on-wafer noise figure measurement system. The result is encouraging and shows promise for future MMIC implementation using the CBCPW structure.
