900 MHz RF Transceiver

AD6190

T he receiver section includes a Low Noise Amplifier (LNA).

T he LNA’s output drives an image-reject mixer; the mixer’s

output optimized for 10.7 MHz is filtered and processed by the

limiting IF amplifier.

28-Lead SSOP Package

T he transmit section accepts a modulated 10.7 MHz IF input,

and uses an image-reject upconverter to mix the signal up to the

902 MHz–928 MHz RF carrier frequency while suppressing the

unwanted image and LO components. T he RF output is raised

to a nominal 0.5 milliwatt (–3 dBm) output level. T his output

can be used directly or can drive an external power amplifier to

higher levels.

T he on-chip VCO operates at 2× the local oscillator frequency.

T his reduces oscillator pulling due to strong interferers in-band

or transmitter leakage. An on-chip 64/65 prescaler allows the

VCO to be controlled by a low cost 15 MHz CMOS synthesizer.

APPLICATIONS

902 MHz–928 MHz ISM Band Cordless Telephones

902 MHz–928 MHz ISM Band Wireless Data System s

An on-chip low dropout regulator minimizes VCO pushing. T he

transmit section, receive section, or both, can be placed in a low

current SLEEP mode when not in use. T he AD6190 900 MHz

RF transceiver is packaged in a 28-lead SSOP package.

GENERAL D ESCRIP TIO N

T he AD6190 900 MHz RF T ransceiver provides a complete

RF/IF section for systems operating in the 902 MHz–928 MHz

license-free ISM band. The high level of integration allows several

dozen discrete components to be replaced. It is ideally suited

for use in cordless telephone and wireless data applications.

T he AD6190 900 MHz RF T ransceiver is part of the Analog

Devices/Zilog “A-to-Z Phone” Spread-Spectrum System for

cordless telephone and data communications applications. Con-
