Features

all the necessary blocks for baseband 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 and 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 via one external resistor. To achieve broadband operation, the Local Oscillator frequency in.
