PRELIMINARY
HFA3766
400MHz AGC Quadrature IF
Modulator/Demodulator
The HFA3766 is a highly integrated
baseband converter for quadrature
modulation applications. It features all
the necessary blocks for baseband
modulation and demodulation of I and
Q signals. It has a two stage integrated AGC IF amplifier with
82dB of voltage gain and 76dB of gain control range.
Baseband antialiasing is integrated into the design. Four
filter bandwidths are programmable via a two bit digital
control interface. In addition, these filters are continuously
tunable over a
±
20% frequency range via one external
resistor. For baseband modulation digital I and Q data are
delivered to the transmit section. To achieve broadband
operation, the Local Oscillator frequency input is required
to be twice the desired frequency of modulation and
demodulation. A selectable buffered divide by 2 LO output
and a stable reference voltage are provided for convenience
of the user. The device is housed in a thin 80 lead TQFP
package well suited for PCMCIA board applications.
