An Integrated Analog Wide-Band Processor with Interference Canceling Capability
Abstract
We propose to develop and demonstrate an integrated analog RF processor capable of eliminating interference signals for wide-band receivers operating from 2-40 GHz. The problem of interference cancelation is challenging for wideband receivers since the dynamic range requirement of signal digitizers depends on the instantaneous signal amplitude. The primary technical objective of this effort is to perform precise excision and cancellation of interferers. The proposed effort addresses wideband interferers that have low spectral density with schemes that automatically trigger on high power spectral density, attenuating only when the power at individual frequencies exceed their threshold. The proposed analog processor will attenuate interference power levels up to 20 dBm potentially by 60 dB, leaving the desired signal undisturbed. We propose an integrated analog processor where all elements are integrated monolithically on single niobium superconducting chip. We envision that the proposed device will operate after the loudest interferers have been attenuated by a preceding device and before the subsequent digitizing section. The proposed effort falls under ONR 6.1 basicresearch, as it introduces novel interference cancelation concepts.
