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. The receiver section includes a Low Noise Amplifier (LNA). The 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. The 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. The RF output is raised to a nominal 0.5 milliwatt (–3 dBm) output level. This output can be used directly or can drive an external power amplifier to higher levels. The on-chip VCO operates at 2 × the local oscillator frequency. This 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. An on-chip low dropout regulator minimizes VCO pushing. The transmit section, receive section, or both, can be placed in a low current SLEEP mode when not in use. The AD6190 900 MHz RF transceiver is packaged in a 28-lead SSOP package. The AD6190 900 MHz RF Transceiver is part of the Analog Devices/Zilog “A-to-Z Phone” Spread-Spectrum System for cordless telephone and data communications applications.
