The RF2938 is a monolithic integrated circuit specifically
designed for direct-sequence spread-spectrum systems
operating in the 2.4GHz ISM band. The part includes a
direct conversion from IF receiver, quadrature demodula-
tor, I/Q baseband amplifiers with gain control and RSSI,
on-chip programmable baseband filters, dual data com-
parators. For the transmit side, a QPSK modulator and
upconverter
are provided. The design reuses the IF
SAW filter for transmit and receive reducing the number
of SAW filters required. Two cell or regulated three cell
(3.6V maximum) battery applications are supported by
the part. The part is also designed to be part of a 2.4GHz
chip set consisting of the RF2444 LNA/Mixer and one of
the many RFMD high efficiency GaAs HBT PA’s and a
dual frequency synthesizer.
