HFA3783 - I/Q Modulator/Demodulator and Synthesizer

Download the HFA3783 datasheet PDF. This datasheet also covers the HFA variant, as both devices belong to the same i/q modulator/demodulator and synthesizer family and are provided as variant models within a single manufacturer datasheet.

Description

PIN NUMBER 1 3 4 6 7 8 9 10 13 NAME RX_VCC IF_RX+ IF_RXTX_VAGC TX_VCC IF_TX+ IF_TXTX_VCC REF_BYP DESCRIPTION Receive AGC Amplifier Power Supply.

Requires high quality capacitor decoupling.

Receive AGC Differential Amplifier Non-Inverting IF Input.

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.
