General Purpose Frequency Conversion
The RF2418 is a monolithic integrated UHF receiver
front-end. The IC contains all of the required components
to implement the RF functions of the receiver except for
the passive filtering and LO generation. It contains an
LNA (low-noise amplifier), a second RF amplifier, a dual-
gate GaAs FET mixer, and an IF output buffer amplifier
which will drive a 50
load. In addition, the IF buffer
amplifier may be disabled and a high impedance output is
provided for easy matching to IF filters with high imped-
ances. The output of the LNA is made available as an
output to permit the insertion of a bandpass filter between
the LNA and the RF/Mixer section. The LNA section may
be disabled by removing the VDD1 connection to the IC.
