4GHZ SPREAD-SPECTRUM TRANSCEIVER Product Description 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 demodulator, I/Q baseband amplifiers with gain control and RSSI, on-chip programmable baseband filters, dual data comparators.
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 frequ...
