DESCRIPTION  
The TRF7900A is a dual integrated RF transceiver designed for human-interface devices (HID). Operating at 27  
MHz, it integrates multiple components (PLL, RF mixer, simulated SAW filter, tuning circuit, and miscellaneous  
passive components) to provide frequency selection from 8 discrete channels. This integration lowers  
component, manufacturing and system costs.

The TRF7900A simplifies system design by reducing system component count and manual circuit tuning. By  
integrating the PLL, SAW filter, and RF mixer, the TRF7900A eliminates the manual tuning of RLC circuits  
required in traditional implementations.
