ATA5773-PXQW

RF Transmitter Overview

The ATA5773-PXQW is a high-performance UHF ASK/FSK RF transmitter IC manufactured by Microchip Technology. It operates within the 310 MHz to 350 MHz frequency band and delivers an output power of 8 dBm. The device supports data rates up to 32 kbps and integrates a PCB surface mount antenna, eliminating the need for external matching components. Packaged in a 24-VQFN with an exposed pad, it is designed for robust wireless transmission applications requiring compact form factors and efficient signal integrity.
