Value Add Hi-Rel

High reliability RF components are an integral part of the Defense and Aerospace industry. The safety of armed forces personnel and the public they serve are dependent upon electronic equipment being able to withstand the challenging environment of today’s battlefield, be it land, sea, air or space.

RFMW, Ltd. offers a wide range of military-qualified RF, microwave and interconnect products (QPL listed; MIL-PRF; MIL-STD). We offer program management and procurement logistics support. Many of our commercial-off-the-shelf (COTS) products can be made available with the additional screening, special handling, or quality assurance testing required for Defense and Aerospace applications. Hermetic packaging options, extended temperature ranges, military standard (MIL-STD) reliability testing, screening for “rad-hard” (radiation-hardened) capabilities, and other engineering support/services make our COTS components and board-level products ideal for this demanding market.

RFMW value-added capabilities increase product yields, reduce labor content, reduce scrap/rework and tuning, reduce field returns, and reduce lead-times by providing one-stop shopping for RF and Microwave value-added services. RFMW offers a complete range of services for commercial, military, and space requirements, including the following:

Key suppliers with parts designed, manufactured, and tested to military standards include TriQuint Semiconductor, Carlisle Interconnect Technologies, Radiall-AEP, Skyworks, Inc., Amplifier Solutions, Aeroflex-Metelics, EMC/Florida RF Labs, MwT Inc., RFMD, Mitsubishi, P1dB and others.

Quality is a priority at RFMW whether it’s product or process related. Our Quality Management System and documented processes are clearly stated and available for customer review and audit.

Value Added Services make RFMW a cut above the typical distributor. We understand your need for on-time delivery and value because we face the same issues on a daily basis. Our focus on RF devices and technology enables us to meet your expectations with the highest service levels.
