RF2958 0 Typical Applications • IEEE 802.11b WLANs • Wireless Residential Gateways • Secure Communication Links Product Description The RF2958 is a single-chip transceiver specifically designed for IEEE 802.11b applications. The part includes all required transceiver functions. The receiver includes: an LNA and downconverter; complete synthesizers and VCO’s; direct conversion from IF receiver with variable gain control; quadrature demodulator; I/Q baseband amplifiers; and, on-chip baseband filters. For the transmit side, a QPSK modulator and upconverter are provided along with the synthesizer, VCO, and PA driver. A minimum number of external components are required, resulting in an ultra-compact low-cost radio design. Twocell or regulated three-cell (3.
