Remote keyless entry, tire pressure monitoring, security sensors and low-power proprietary sub-GHz links.
Compact receiver modules that need a low external component count and serial data output in common 315 MHz or 433.92 MHz bands.
Quality & Sourcing
Antrex Electronics can support sourcing for MICRF219AAYQS through available stock checks, BOM consolidation and alternative-lot review. For RF receiver and radio receiver parts, package condition, lot/date code, moisture handling and original labeling should be checked before shipment.
For shortage support or legacy builds, 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, allocated or hard-to-find receiver ICs and modules.
