TDK5110FHTMA1

RF Transmitter Overview

The TDK5110FHTMA1 is a single-chip ASK/FSK RF transmitter IC manufactured by Infineon Technologies, designed for operation in the 433–435 MHz frequency band. It delivers an output power of 11 dBm and supports data rates up to 20 kbps. The device operates on a supply voltage range of 2.1 V to 4 V with a typical transmission current of 14.2 mA. It is housed in a compact 10-TFSOP or 10-MSOP package (PG-TSSOP-10-3) suitable for surface-mount PCB assembly. The component functions as a complete transmitter solution requiring minimal external components.

RF Transmitter Procurement Notes

Verify part status carefully as this component is listed as obsolete. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing design constraints given the discontinued status. Check for valid RoHS3 compliance documentation if required for specific regulatory environments. Validate package dimensions against current PCB footprint specifications before procurement.

RF Transmitter Selection Notes

Select this component for applications requiring simple ASK or FSK transmission at 434 MHz. Consider the low supply voltage range for battery-powered designs. Evaluate the 11 dBm output power against link budget requirements. Assess the 10-TFSOP package size for space-constrained layouts. Verify that the 20 kbps data rate meets system throughput needs.

RF Transmitter Part Context

This part belongs to the TDK5110 series of RF transmitters from Infineon Technologies. It shares functional similarities with other models in the family but differs in specific frequency bands and performance parameters. The series targets low-cost, low-power wireless communication solutions. Understanding the broader family helps in identifying potential alternative parts with similar pinouts or functionalities.
