Dual-Band Transmitter and Receiver With Bowtie-Antenna in 0.13 μm SiGe BiCMOS for Gas Spectroscopy at 222 - 270 GHz

This paper presents a transmitter (TX) and receiver (RX) with bowtie-antenna silicon lens for gas spectroscopy at 222-270 GHz, which are fabricated in IHP’s 0.13 μm SiGe BiCMOS technology. The TX RX use two integrated local oscillators 222 – 256 GHz 250 270 switched dual-band operation. Due to its directivity of about 27 dBi, the single enables an EIRP 25 dBm TX, therefore considerably higher 2-band compared previously reported systems. double sideband noise temperature is 20,000 K (18.5 dB figure) as measured by Y-factor method. Absorption gaseous methanol used measure performance system TX- RX-modules.
