TRF5901PT

Overview

The TRF5901PT is a single-chip RF transceiver manufactured by Texas Instruments, designed for ISM band applications below 1 GHz. It operates within the frequency range of 902 MHz to 928 MHz and supports data rates up to 100 kbps. The device features an output power of 4.5 dBm and supports ASK, FSK, and OOK modulation schemes. It utilizes SPI serial interfaces for control and communication. The component is housed in a 48-LQFP surface-mount package and draws a maximum current of 28 mA during operation.

Feature Summary

• Integrates transmitter and receiver functions into a single chip solution
• Supports multiple modulation formats including ASK, FSK, and OOK
• Utilizes standard SPI interface for configuration and control

Applications

• ISM band wireless sensor networks
• Remote keyless entry systems
• Short-range telemetry links

Procurement Notes

Verify the specific suffix (PT) corresponds to the required tape and reel packaging format when ordering. Confirm that the 48-LQFP footprint matches the target PCB layout dimensions. Ensure the operating voltage and current specifications align with the system power budget before finalizing procurement.

Selection Notes

Select this component for designs requiring integrated transmission and reception capabilities within the sub-1 GHz spectrum. Consider the 100 kbps data rate limit when evaluating throughput requirements. The 4.5 dBm output power may necessitate external amplification for extended range applications.
