RF2418PCBA(Rec_A6) 데이터시트 - RF Micro Devices

Product Description
The RF2418 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, 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 insertion 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.
