Product Description

The RF2494 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.
