Applications

WCDMA, CDMA, TD-SCDMA, GSM, WiMAX/LTE, software-defined radio and broadband RF transmitter designs.

Direct upconversion transmit paths that need broad 400 MHz to 4 GHz RF coverage with high I/Q modulation quality.

Quality & Sourcing

Antrex Electronics can support sourcing for TRF370317IRGET through available stock checks, BOM consolidation and alternative-lot review. For RF modulator ICs and modules, package condition, date code, MSL handling and original labeling should be checked before shipment.

For shortage support, legacy repair or project 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 RF modulator parts.
