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 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.
