Abstract :
A frequency-agile, low-power 3-5 GHz FM transceiver with on-chip calibration, and digital control of Rx gain, Tx power, and carrier frequency is described. The FCC-compliant transmitter incorporates a 3-phase CCO and frequency-tripling PA. A tunable LNA, envelope detector, limiter, and FSK demodulator comprise the receiver. Measured Rx sensitivity is -80.5 dBm (10-3 BER) at 100 kb/s. The 0.9 mm2 IC fabricated in 90 nm RF-CMOS dissipates 630 μW in Tx and 580 μW in Rx mode from a 1 V supply.
