REV 1.3 Page 1 of 4 Copyright © 2019 1.0mm male to 1.85mm female adapter part number SM3978 from Fairview Microwave is in-stock and ships same day. This Fairview 1.0mm to 1.85mm adapter has a male to female gender configuration. SM3978 1.0mm male to 1.85mm female adapter operates to 65 GHz. The Fairview Microwave RF adapter provides good VSWR of 1.35:1 maximum. RF adapters can be used to enable connections between two connector types that would otherwise not mate. Certain RF adapter configurations can also be used to protect connectors on expensive equipment where the number of connect and disconnect cycles is high. An RF, microwave, or millimeter wave adapter is connected to the equipment and the commonly changed connection is made with the adapter which can be easily replaced when it wears out after high usage; such adapters are referred to as connector savers. Fairview Microwave also offers bulkhead, panel mount, hermetically sealed, reverse polarity, and isolated ground adapter varieties to serve all of your RF, microwave and millimeter wave needs.
