● Fast Transmit-Receive Switching . . . . . . . . . . . . . . . . . It features all the necessary blocks for baseband modulation and demodulation of I and Q signals. It has a two stage integrated limiting IF amplifier with 84db of gain with a built in Receive Signal Strength Indicator (RSSI). 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. The modulator channel receives digital I and Q data for processing.
