HFA3726
400MHz Quadrature IF
Modulator/Demodulator
The HFA3726 is a highly integrated
baseband converter for quadrature
modulation applications. It features all
the necessary functionality for
baseband modulation and
demodulation of I and Q signals. It has a two stage
integrated limiting IF amplifier with 84dB of gain and a built in
Receive Signal Strength Indicator (RSSI). “I” and “Q”
Baseband antialiasing and shaping filters are integrated in
this design. In addition, these filters are continuously tunable
over a
±
10% frequency range via one external resistor. The
modulator channel receives digital I and Q data for
processing. To achieve broadband operation, the Local
Oscillator frequency input is required to be twice the desired
frequency of modulation/demodulation. A selectable
buffered divide by 2 LO output and a stable reference
voltage is provided for convenience of the user. The device is
housed in a thin 80 lead TQFP package well suited for
PCMCIA board applications.
