Applications

Point-to-point radios, VSAT radios, fiber optic links, synthesizers and microwave test equipment.

PLL and prescaler replacement projects where the HMC492 divide ratio, 5 V bias and 3x3 mm QFN layout must match.

Quality & Sourcing

Antrex Electronics can support sourcing for HMC492LP3ETR through available stock checks, BOM consolidation and alternative-lot review. For RF and microwave ICs, package markings, moisture sensitivity, date code and original labeling should be checked before shipment.

For shortage coverage, repair builds or production support, Antrex Electronics can coordinate visual inspection, package verification and third-party testing when required. This helps buyers reduce risk when sourcing discontinued, legacy or hard-to-find RF miscellaneous ICs and modules.
