A direct conversion 4.9GHz to 5.925GHz OFDM receiver with Matched Non-Integer Quadrature LO

A direct conversion 4.9 GHz to 5.925 GHz OFDM receiver IC with non-integer matched quadrature LO that supports channel bandwidths from 1 MHz to 28 MHz is manufactured on Jazz 0.35 mum BiCMOS process. This chip has a noise figure less than 6 dB and Input P1 dB of greater than -14 dBm at maximum gain. The I/Q gain mismatch is less than 0.15 dB and phase error is less than 3degree without any calibration during manufacturing or feedback from baseband.
