I/Q Modulator/Demodulator and Synthesizer
The HFA3783 is a highly integrated and fully differential SiGe baseband converter for half duplex wireless applications. It features all the necessary blocks for quadrature modulation and demodulation of “I” and “Q” baseband signals. It has an integrated AGC receive IF amplier with frequency response to 600MHz. The AGC has 70dB of voltage gain and better than 70dB of gain control range. The transmit output also features gain control with 70dB of range. The receive and transmit IF paths can share a common differential matching network to reduce the lter component count required for single IF half duplex transceivers.
