Features

  • all the necessary functionality for baseband modulation and demodulation of I and Q signals. It has a two stage integrated limiting IF amplifier with 84dB of gain and a built in Receive Signal Strength Indicator (RSSI). “I” and “Q” Baseband antialiasing and shaping filters are integrated in this design. In addition, these filters are continuously tunable over a ±10% frequency range via one external resistor. The modulator channel receives digital I and Q data for processing. To achieve broadband op.
