Preliminary 8 Typical Applications • Part of 2.4GHz IEEE802.11b WLANs • Digital Communication Systems RF2494 HIGH FREQUENCY LNA/MIXER • WLAN or Wireless Local Loop • Portable Battery-Powered Equipment • Spread-Spectrum Communication Systems • UHF Digital and Analog Receivers Product Description The RF2494 is a monolithic integrated UHF receiver front end suitable for 2.4GHz ISM band applications. 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 and a doubly balanced mixer. 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.
