Abstract
This paper presents a fully-integrated ultra wide bandreceiver MMIC for high data rate communication at 240 GHz operating with a LO frequency of 60 GHz. The chip was fabricated in a 35 nm InGaAs-based metamorphic high electron mobility transistor technology. It comprises a frequency doubler followed by a buffer amplifier in the LO path, a LNA in the RF path and a subharmonic single balanced down converter on a single chip. The receiver achieves a peak conversion gain of 16 dB without IF amplification and a 3 dB-bandwidth of 32 GHz in a RF frequency range of 220 to 252 GHz.
