Low Noise Amplifier RF Input, internally DC coupled and requires an external blocking capacitor.

Features

  • a low noise, gain selectable amplifier (LNA) followed 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.

HFA3683A TM Data Sheet June 2000 File Number 4634.5 2.4GHz RF/IF Converter and Synthesizer The HFA3683A is a monolithic SiGe half-duplex RF/IF transceiver designed to operate in the 2.4GHz ISM band. The receive chain features a low noise, gain selectable amplifier (LNA) followed 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. 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.
