چکیده
This paper focuses on InP-based, HEMT Monolithic Millimeter-wave Integrated Circuit (MMIC) power amplifiers for applications to heterodyne receivers, transmitters, and communications circuits. Recently, we have developed several HEMT MMIC circuits using HRL Laboratories' 0.1 um InP HEMT technology with unprecedented high frequency performance and output power. Our results include an 80 GHz bandwidth power amplifier to 145 GHz, a 15-25 mW amplifier to 170 GHz and a HEMT active doubler to 300 GHz, the highest frequency HEMT doubler circuit reported to date. We will report on the design and testing of the circuits, and discuss the methods involved in measuring MMICs above 200 GHz. These circuits are particularly useful in local oscillators for heterodyne receivers at THz frequencies.
