Abstract

This paper describes a compact, efficient and highly sensitive 1 GHz superheterodyne receiver which can track, receive and detect frequency modulation (FM), and frequency shift keying (FSK) signals with a modulation bandwidth of 200 kHz and a sensitivity threshold of 500 nV. The tracking bandwidth of 500 kHz allows reliable operation over the temperature range of (-30...+60) deg. C. The receiver can process FSK signals with a data rate in excess of 200 kbit/s, draws a current of 12 mA from a 3.5 V direct current (DC) source and has the dimensions of 100×50×12 mm with batteries included. The key to achieving this receiver performance in such a small volume is the utilization of novel surface transverse wave (STW) technology which allows the design of compact and temperature stable local oscillators (LO) featuring excellent tunability and superior phase noise performance
