Patent ID: 8346202

Claim:
An apparatus comprising: a mixer to downconvert incoming radio frequency (RF) signals to complex second frequency signals; a first programmable gain amplifier (PGA) coupled to the mixer to receive and amplify a first complex second frequency signal; a second PGA coupled to the mixer to receive and amplify a second complex second frequency signal; a first passive filter coupled to the first PGA to filter the amplified first complex second frequency signal; a second passive filter coupled to the second PGA to filter the amplified second complex second frequency signal; a digital circuit including digitization circuitry to convert the filtered first and second complex second frequency signals into digital complex signals, a digital signal processor (DSP) coupled to the digitization circuitry to channel filter the digital complex signals, and conversion circuitry to convert the channel filtered digital complex signals to analog signals; and output buffer circuitry to buffer the analog signals for output from the apparatus.
