General Purpose Frequency Conversion
The RF2431 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. Alternatively, the IF output
may be matched to a higher impedance at significantly
reduced current. 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 out-
put is buffered to permit a wide range of choices for the
interstage filter without altering the VSWR or noise figure
at the LNA input and to provide high isolation from the LO
to the input port.
