Wireless communication device and method for wideband spectrum monitoring

Abstract

A wireless communication device includes an RF input to receive RF signals in a range of DC to 300 GHz. The wireless communication device includes an RF front-end with a plurality of band filters to apply band-specific filtering operation to the received RF signals to obtain filtered RF signals. A local oscillator generates tunable local oscillator frequencies above a threshold frequency. The wireless communication device includes circuitry to execute a frequency shifting operation in one or more frequency conversion stages, and a processor that concurrently processes the digitized down-converted signals across predefined intermediate frequencies to perform real-time or near real-time enhanced spectrum monitoring operations.
