Abstract:
1. A radio frequency receiver comprising: a receiver module which receives a radio frequency (“RF”) signal and provides a baseband in-phase (“I”) signal and a baseband quadrature (“Q”) signal, eliminates a sideband of said I signal and a sideband of said Q signal to create a first and a second signal, downconverts said first and second signal to a first and a second intermediate frequency (“IF”) signal, and selects one of said first or second IF signals; an IF module which receives said first or second IF signal, performs analog-to-digital conversion on said first or second IF signal, and demodulates said digitally converted IF signal; a synthesizer module which receives a programmable reference signal, downconverts said reference signal to an IF feedback signal, downconverts said reference signal to a baseband feedback signal, provides said IF feedback signal to said IF module, and provides said baseband feedback signal to said receiver module; a controller module comprising an integrated circuit configured to sample said digitally converted IF signal, said integrated circuit comprising a numerically controlled oscillator configured to provide said programmable reference signal to said synthesizer module; and a temperature compensation module configured to regulate temperature of said radio frequency receiver based on temperature sensed from said IF module; said controller module configured to provide a demodulated output signal derived from said digitally converted IF signal.
