2.4GHz RF/IF Converter and Synthesizer

Features

The HFA3683A is a monolithic SiGe

half-duplex RF/IF transceiver designed

to operate in the 2.4GHz ISM band.

• Highly Integrated

• Multiplexed RX/TX IF Path Utilizes Single IF Filter

• Programmable Synthesizer

The receive chain features a low noise,

gain selectable ampliﬁer (LNA) followed

• Gain Selectable LNA

by a down-converter mixer. An up-converter mixer and a

high performance preampliﬁer compose the transmit chain.

The remaining circuitry comprises a high frequency Phase

Locked Loop (PLL) synthesizer with a three wire

programmable interface for local oscillator applications.

• Power Management/Standby Mode

• Single Supply 2.7V to 3.3V Operation

A reduced ﬁlter count is realized by multiplexing the receive

and transmit IF paths and by sharing a common differential

matching network. Furthermore, both transmit and receive

RF ampliﬁers can be directly connected to mixers. The

inherent image rejection of both the transmit and receive

functions allow this economic advantage.

The HFA3683A is housed in a 64 lead TQFP package well

suited for PCMCIA board applications.
