RF2958

2.4GHz SPREAD-SPECTRUM TRANSCEIVER

• IEEE 802.11b WLANs

• Wireless Residential Gateways

• Secure Communication Links

• High Speed Digital Links

• Wireless Security

• Digital Cordless Telephones

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 synthe-

sizers and VCO’s; direct conversion from IF receiver with

variable gain control; quadrature demodulator; I/Q base-

band 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. Two-

cell or regulated three-cell (3.6V maximum) battery appli-

cations are supported by the part. The RF2958 is also

part of a 2.4GHz chipset along with our high-efficiency

GaAs HBT PA and the RF3002 Baseband Processor.

• Complete IEEE802.11b Transceiver

including VCOs

• Small 32-pin Leadless Package

• Minimal External Components Required

• Low Receive Current

• High Performance Super-het Architecture
