HFA3763 Features

* all the necessary blocks for baseband modulation of I and Q signals. An output AGC and Baseband shaping ﬁlters are integrated in 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
