File Number 4633.2

I/Q Modulator/Demodulator and

Synthesizer

Features

• Integrates All IF Transmit and Receive Functions

• Broad Quadrature Frequency Range . . . . . .70 to 600MHz

• 600MHz AGC IF Strip with Level Detector . . . . . . . . .69dB

• DC Coupled Baseband Interfaces

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.

• Integrates a Receiver DC Offset Calibration Loop

• Integrated 3 Wire Interface PLL For LO Applications

• Low LO Drive Level . . . . . . . . . . . . . . . . . . . . . . . -15dBm

• Fast Transmit-Receive Switching . . . . . . . . . . . . . . . .<1µs

• Power Management/Standby Mode

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.

• Single Supply 2.7 to 3.3V Operation

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.

Applications

• IEEE802.11 1 and 2Mbps Standard

• Systems Targeting IEEE 802.11 11Mbps Standard

• Wireless Local Area Networks

• PCMCIA Wireless Transceivers

• ISM Systems

• TDMA Packet Protocol Radios

Ordering Information

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.
