1.35 mm DC to 90 GHz connectors from Southwest Microwave include a field-replaceable 4-hole Flange-mount Connector, standard Thread-in Connector, Cable Connector, clamp-on solderless End Launch Connector, Solderless Vertical Launch Connector, and between series adaptors.

High frequency reed relays are engineered for precision signal switching from DC up to 8 GHz, making them ideal for RF, microwave, and high-speed digital applications. These relays feature ultra-short signal paths and internal coaxial shielding with consistent 50 Ohm impedance, ensuring minimal insertion loss and excellent signal integrity. With rise times under 40 picoseconds and low contact resistance, they support fast pulse switching and high isolation in compact designs. Available in surface-mount packages with advanced shielding, they are optimized for automated test equipment, wireless systems, and high-frequency PCB layouts.

Our surface mount SMD reed switch products feature a bare, hermetically sealed glass envelope designed for reliability and precision. With five distinct surface mount lead designs, these switches offer enhanced flexibility for various PCB layouts and applications.

Magnetically actuated, these reed switches are ideal for both switching and sensing functions across a wide range of industries, from automotive and medical to industrial and consumer electronics.

We offer nine different switch models, with glass lengths starting as small as 7 mm, and a variety of switching configurations. Choose from power ratings up to 100 W and switching voltages reaching 1,000 VDC, tailored to meet your specific performance requirements.

For streamlined manufacturing, our SMD reed switches are typically supplied in tape and reel packaging per IEC 286/Part 3, making them compatible with automatic pick-and-place equipment.
