Applications

RKE, TPMS-style sensors, garage-door openers, alarms and low-power ISM-band data receivers requiring ASK/FSK support.

Legacy sub-GHz receiver boards using Infineon TDA5210 for either 400 MHz or 800 MHz band operation.

Quality & Sourcing

Antrex Electronics can support sourcing for TDA5210T through available stock checks, BOM consolidation and alternative-lot checking. For RF receiver ICs, lot/date code, package condition, moisture sensitivity handling and original labeling should be checked before shipment.

For project builds or shortage support, Antrex Electronics can coordinate visual inspection, packaging verification and third-party electrical or authenticity testing when required. This helps buyers manage risk when sourcing discontinued, legacy or hard-to-find RF receiver parts.
