RF Transmitters

Radio frequency (RF) transmitters are devices that systematically produce and amplify low-power electromagnetic signals for the purpose of wireless communication. They are used in most wireless communication systems, ranging from broadcast systems such as AM and FM radio, television networks, telecommunication networks, and two-way radio systems. The ATA8743C-PXQW is used for both short-range and long-range applications.

ATA8743C-PXQW Application Fields

The ATA8743C-PXQW is a cost-effective integrated radio frequency (RF) / microwave transmitter module designed for applications operating in the 118 to 960 MHz frequency range. It can be used for a variety of applications such as short-range point-to-point communication and long-range broadcast systems. It is especially well suited for low and medium power radio broadcast applications. The device can be used for both narrowband and Wideband FM (WBFM) applications. It also can be utilized for time-sharing link systems such as Digital Audio Broadcasting (DAB) and Digital Video Broadcasting (DVB). Moreover, its features make it well-suited for use in radio telemetry systems.

ATA8743C-PXQW Working Principle

The ATA8743C-PXQW is an integrated transmitter module that combines an RF/microwave frequency synthesizer, an RF amplifier, and a power amplifier into a single package. It utilizes synthesis techniques to produce highly stable RF signals over a wide range of frequencies. The device contains on-board frequency-setting and control circuitry, which allows for rapid and accurate frequency selection. The on-board amplifier stages are designed to provide a linear signal amplification, while simultaneously minimizing distortions.

The ATA8743C-PXQW also features an on-board temperature sensor that enables it to compensate for temperature-induced frequency-drifts of the synthesizer. This ensures that the synthesizer output remains constant over a wide range of temperatures. In addition, the device is equipped with a wide range of power output stages with power levels ranging from +10 dBm to +45 dBm, allowing for easy system integration.

The ATA8743C-PXQW transmitter module is designed to be used in a wide variety of applications where reliable transmission of signals is essential. With its wide range of frequencies, linear amplifier stages, temperature compensated circuitry, and a comprehensive range of power outputs, the device provides an excellent platform for both short-range and long-range radio transmission applications.
