Abstract

A 245 GHz sensor system for gas spectroscopy is presented, which includes a SiGe transmitter (TX) and a receiver (RX). The integrated local oscillators of TX- and RX-chips are controlled by two external phase-locked loops (PLL), whose reference frequencies are swept with constant frequency offset. The reference frequency of the TX-PLL is modulated for frequency-modulation spectroscopy. The performance of the sensor system is demonstrated by the 2f absorption spectrum (second harmonic detection) of methanol.
