Product Description
The RF2418 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, a dual-gate GaAs FET
mixer, and an IF output buffer amplifier which will drive a 50Ω load. In
addition, the IF buffer amplifier may be disabled and a high impedance
output is provided for easy matching to IF filters with high impedances.
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 RF/Mixer section. The
LNA section may be disabled by removing the VDD1 connection to the IC.
