Announcement | Watech Electronics RF PA Products Support Customers in Smoothly Navigating Supply Chain Risks

Recent disruptions in the global supply of certain radio frequency power amplifiers (PAs) are impacting multiple sectors, including wireless telecommunications, broadcasting, and medical and industrial equipment. These challenges threaten supply chain stability and product development timelines for downstream customers.

Watech Electronics is addressing this issue directly with a comprehensive portfolio of alternative RF PA solutions, designed to ensure our customers' business continuity.

I. Watech's Response: Ready-to-Deploy Alternative Solutions

In response to these market dynamics, Watech immediately activated our contingency plans. We have now completed the development and validation of full-series alternative solutions for the affected RF PA products. Updated product information, including datasheets and application notes, is available on our official website.

Our alternative solutions are engineered for a seamless transition and offer key advantages:

l   Package Compatibility: Key models use the same package formats (e.g., SOT-89, QFN) as the original parts, enabling rapid replacement without PCB redesign.

l   Supply Assurance: We have secured inventory for the full series and established expedited shipping channels to prioritize urgent orders.

l   Certification Support: All alternatives have passed rigorous reliability testing and comply with RoHS and REACH standards, supported by complete application notes and test reports.
