CXA1742Q

CXA1742Q IF Amplifier for Analog Cellular Communications For the availability of this product, please contact the sales office. Description The CXA1742Q is an analog cellular(AMPS) FM IF IC which include an IF filter. Features Include a ceramic filter function, which is normally mounted externally. Quadrature detection discriminator function. This IC has almost all IF functions and is ideal for reduction in set size because of few external parts required. Channel filter conforming to the AMPS standard. Wide operating voltage range (2.7 V to 3.6 V) and low current consumption (Icc=10 mA (typ.) when Vcc= 3 V). Wide range and excellent temperature characteristics for the RSSI (receiving signal strength indicator). Applications Ideally suited for cellular phones, particularly handheld sets.
