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 50Ω load. 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).
