UHF Digital and Analog Receivers
The RF2444 is a monolithic integrated UHF receiver front
end suitable for 2.4GHz ISM band applications. The IC
contains all of the required components to implement the
RF functions of the receiver except for the passive filter-
ing and LO generation. It contains an LNA (low-noise
amplifier), a second RF amplifier and a doubly balanced
mixer. The output of the LNA is made available as an out-
put to permit the insertion of a bandpass filter between
the LNA and the RF/Mixer section. The mixer outputs can
be selectively disabled to allow for the IF filter to be used
in the transmit mode.
