com • UHF Digital and Analog Receivers • Digital Communication Systems • Commercial and Consumer Systems • Portable Battery Powered Equipment • Spread Spectrum Communication Systems • General Purpose Frequency Conversion 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 contains 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 balanced mixer, an LO buffer amplifier, and an IF output amplifier which will drive a 50 Ω load.
The output of the LNA is made available as an output to permit the insertion of a bandpass filter between the LNA and the attenuator.
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).
