Abstract

An apparatus, which may be configured as a receiver or transceiver, includes a plurality of super regenerative (SR) amplifiers coupled in parallel, wherein the SR amplifiers are tuned to distinct frequency bands, respectively. The apparatus may further include isolation amplifiers at the respective inputs and outputs of the SR amplifiers to prevent injection locking and reduce power leakage. The apparatus may include a circuit to reduce or substantially eliminate in-band jamming signals. The apparatus may form at least part of a wireless communications device adapted to receive signals from other wireless communications devices, adapted to transmit signal to other wireless communications devices, and adapted to both transmit and receive signals to and from other wireless communications devices.
