HFA3783 General Description
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 amplifier 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 filter component count required for single IF half duplex transceivers. A pair of 2nd order antialiasing filters with an integrated DC offset cancellation architecture is included in the receive chain for baseband operation down to DC. In addition, an IF level detector is included in the AGC chain for threshold comparison. Up and down conversion are performed by doubly balanced mixers for "I" and "Q" IF processing. These converters are driven by a broadband quadrature LO generator with frequency of operation phase locked by an internal 3 wire interface synthesizer and PLL.
The device operates at low LO levels from an external VCO with a PLL reference signal up to 50MHz. The HFA3783 is housed in a thin 48 lead LQFP package well suited for PCMCIA board applications.
