RF2411
LOW NOISE AMPLIFIER/MIXER
The RF2411 is a monolithic integrated UHF receiver front-end. The IC con-
tains 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, and a balanced mixer
which can drive a single-ended or balanced load. The output of the LNA is
made available as a pin to permit the insertion of a bandpass filter
between the LNA and the RF/Mixer section. The LNA output 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. The LNA section may be disabled to conserve
power.
