AD6190 - 900 MHz RF Transceiver

General Description

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.

Key Features

  • Complete 900 MHz RF Transceiver LNA Receive Mixer Transmit Mixer Driver Amplifier VCO Prescaler Limiter Amplifier with RSSI On-Chip Low Dropout Regulator Independent Sleep Modes for TX, RX 28-Lead SSOP Package.

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.
