Intersil HFA3861
The HFA3861 has on-board A/D’s for analog I and Q inputs and outputs, for which the HFA3783 IF QMODEM is recommended. Both Receive and Transmit AGC functions with 7-bit AGC control obtain maximum performance in the analog portions of the transceiver. The HFA3861 is housed in a thin plastic quad flat package (TQFP) suitable for PCMCIA board applications.FEATURES
