Abstract:
The disclosure relates to technology for a receiver having a receive signal path including a mixer, a differential fixed gain or variable gain amplifier, and a differential filter. The mixer is configured to receive an RF signal, receive an oscillator signal, and output a differential down converted signal at one of a baseband or intermediate frequency (IF). The amplifier is downstream of the mixer and configured to receive the differential down converted signal from the mixer, apply a gain thereto, and output an amplified differential signal. The filter is downstream of the amplifier and configured filter the amplified differential signal received from the amplifier, and output a filtered differential signal. By locating the differential filter downstream of the differential amplifier within the receive signal path, distortion caused by the mixer is mitigated compared to if the filter were located upstream of the filter.

Claim (Index 1):
A receiver, comprising:\n a mixer coupled to receive an RF signal and a local oscillation signal, and configured to produce a differential down converted signal at one of a baseband or intermediate frequency (IF); a differential variable gain amplifier (VGA) coupled downstream of the mixer and coupled to receive the differential down converted signal produced by the mixer, and configured to produce an amplified differential signal; and a differential filter coupled downstream of the differential VGA and coupled to receive the amplified differential signal from the differential VGA, and configured to filter the amplified differential signal, and produce a filtered differential signal; the differential VGA including differential input terminals, differential output terminals, and signal processing circuitry between the differential input terminals and the differential output terminals of the VGA; and the differential VGA also including first and second cross-coupled segments, the first cross-coupled segment coupled between the differential input terminals of the VGA and a negative (\u2212) input of the signal processing circuitry, and the second cross-coupled segment coupled between the differential input terminals of the VGA and a positive (+) input of the signal processing circuitry; wherein the mixer, the differential VGA, and the differential filter are each part of a receive signal path of the receiver and are coupled in that sequential order.
