Applications

Microwave PLLs, VSAT radios, point-to-point links, fiber optic equipment and RF test instrumentation.

Frequency-control cards that need a fixed divide-by-4 prescaler with low additive phase noise and the HMC493 footprint.

Quality & Sourcing

Antrex Electronics can support sourcing for HMC493LP3 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.
