A wireless receiver includes an antenna panel coupled to an H-combined/V-combined generation block, an axial ratio and cross-polarization calibration block to correct for an undesired variation in H-combined and V-combined outputs, and an LHCP/RHCP generation block to produce left-handed circularly polarized (LHCP) and right-handed circularly polarized (RHCP) outputs. The axial ratio and cross-polarization calibration block generates an H-corrected output by summing the H-combined output amplified by a first variable gain amplifier and the V-combined output amplified by a second variable gain amplifier, and a V-corrected output by summing the V-combined output amplified by a third variable gain amplifier and the H-combined output amplified by a fourth variable gain amplifier.
