RF2418

RF2418 8 Typical Applications UHF Digital and Analog Receivers Digital Communication Systems Commercial and Consumer Systems 433MHz and 915MHz ISM Band Receivers LOW CURRENT LNA/MIXER Spread-Spectrum Communication Systems General Purpose Frequency Conversion 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 dualgate GaAs FET mixer, and an IF output buffer amplifier which will drive a 50 Ω 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. 0.156 0.148 .018 .014 0.010 0.004 0.347 0.339 0.050 0.252 0.236 0.059 0.057 8° MAX 0° MIN 8 0.010 0.007 0.0500 0.0164 Optimum Technology Matching® Applied Si BJT Si Bi-CMOS GaAs HBT SiGe HBT ü Package Style: SOIC-14 GaAs MESFET Si CMOS Features Single 3V to 6.5V Power Supply High Dynamic Range LNA LNA IN 1 GND 2 VDD1 3 VDD2 4 10pF IF BYP 5 IF2 OUT 6 IF1 OUT 7 10 GND 9 DEC MIXER 8 LO IN 14 LNA OUT Low Current Drain 13 GND 12 GND 11 RF IN High LO Isolation ...
