Single Chip Transceiver For 2.45 Ghz Ism Band - Nxp Semiconductors

The SA2400A is a fully integrated single IC RF transceiver designed for 2.45 GHz Wireless LAN (WLAN) applications. It is a direct conversion Radio architecture that is fabricated on an advanced 30 GHz fT BiCMOS process. The SA2400A combines a receiver, transmitter, and LO generation into a single IC. The receiver consists of a low-noise Amplifier down-conversion mixers, fully integrated channel Filters and an Automatic Gain Control (AGC) with an on-chip closed loop. The transmitter contains power ramping, Filters up-conversion, and pre-drivers. The LO generation is formed by an entirely on-chip VCO and a fractional-N synthesizer. Typical system performance parameters for the receiver are 93 dB gain, 7.5 dB noise figure, input-referred third-order intercept point (IIP3) of +1 dBm, AGC settling time of 8 s, and Tx-to-Rx switching time of 3 s. The transmitter typical system performance parameters are an output power range from 7 dBm to +8 dBm in 1 dB steps, 40 dBc Carrier leakage after calibration, 22 dB sideband suppression, in-band common mode rejection of 30 dB, and Rx-to-Tx switching time of 3 s.
