The RF2401 is a monolithic integrated UHF receiver
front-end. The IC contains all of the required components
to implement the front-end functions of the receiver
except for the passive filtering and LO generation. It con-
tains a high dynamic range LNA (low-noise amplifier), an
attenuator to reduce signal level in the presence of large
received signals, a second RF amplifier, a double bal-
anced mixer, an LO buffer amplifier, and an IF output
amplifier which will drive a 50load. The output of the
LNA is made available as an output to permit the inser-
tion of a bandpass filter between the LNA and the attenu-
ator. The mixer input is buffered to provide high isolation
from the LO to the input port. Blocking capacitors are
contained on the chip (except for the IF Output).

In order to achieve a low VSWR match at
this input, a 10nH chip inductor is placed in
series with this port. If direct coupling is used
(no noise image filter between LNA OUT and
RF IN ports), no inductor is necessary.
