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.
