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 hand-
held sets.
