TDK5111XUMA1

RF Transmitter Overview

The TDK5111XUMA1 is an RF transmitter IC manufactured by Infineon Technologies, designed for ASK modulation in the 314MHz to 317MHz ISM band. It operates on a single supply voltage ranging from 2.1V to 4V and delivers a typical output power of 3.2dBm. The device supports data rates up to 20kbps and features a low current consumption of approximately 7mA during transmission. Packaged in a 16-TSSOP surface-mount housing, it is intended for integration into compact wireless systems requiring reliable short-range communication capabilities.

RF Transmitter Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm end-of-life status and availability constraints prior to procurement planning. Ensure storage conditions comply with moisture sensitivity level requirements to maintain solderability and reliability during assembly processes.

RF Transmitter Selection Notes

Select this component for applications requiring fixed-frequency ASK transmission in the 314-317MHz range. Evaluate system power budget against the 7mA transmit current requirement. Consider the integrated antenna feature if PCB trace antennas are preferred over discrete components. Verify compatibility with host microcontroller interface requirements for data encoding.

RF Transmitter Part Context

This part belongs to Infineon's TDK series of RF transmitters, which are optimized for cost-effective and low-power wireless solutions. The series typically targets ISM band applications where simple modulation schemes like ASK are sufficient. These components integrate the RF frontend and oscillator to reduce bill of materials complexity.
