Abstract :
A BiCMOS transceiver intended for spread spectrum applications in the 2.4-2.5 GHz band is described. The IC contains a low-noise amplifier (LNA) with 14 dB gain and 2.2 dB NF in its high-gain mode, a downconversion mixer with 8 dB gain and 11 dB NF, and an upconversion mixer with 17 dB gain and P-1 dB of +3 dBm out. An on-chip local oscillator (LO) buffer accepts LO drive of -10 dBm with a half-frequency option allowed by an on-chip frequency doubler. Power consumption from a single 3-V supply is 34 mA in transmit mode, 21 mA in receive mode, and 1 μA in sleep mode
