HFA3766 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 dig
