Product Description
The RF2411 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, and a
balanced mixer which can drive a single-ended or bal-
anced 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 inter-
stage 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 con-
serve power.
