A wideband interference tolerant RF receiver for cognitive radio sensor unit
A wideband receiver for cognitive radio spectrum sensing unit is presented. The circuit consists of a high linearity low noise amplifier, passive mixer, and baseband buffer. IQ signals for the LO are generated using a divide-by-two circuit. Low noise amplifier includes common-gate common-source combination for simultaneous interference suppression and noise canceling. The receiver operates in the LTE bands at 0.7 - 2.6 GHz, with typical performance of 32 dB gain, 5 dB noise figure, and IIP3 linearity between 5 dBm and -1 dBm in the LTE bandwidth. The circuit is designed for 65-nm CMOS technology.
