COAXIAL REED RELAYS FOR RF SIGNAL SWITCHING AND HIGH-SPEED DIGITAL SWITCHING

Reed Relays are an excellent choice for RF Signal Switching, RF switched tuneable filters, and High-Speed Digital Switching due to their speed and size when compared to Electromechanical Relays, lower insertion loss and DC capability when compared to Solid State Relays, and hot switching capability when compared with Micro Electromechanical Machines.

Please take a look at Pickering’s 50Ω and 75Ω HF coaxial reed relays below. These high-frequency reed relays are suitable for up to 5 GHz. Available in through-hole or surface mount.

Coaxial RF Reed Relays for RF Switching

RF Reed Relay Series 102

Series 102M up to 1.5 GHz

Available in 1 Form A or 1 Form B configurations. 3, 5 or 12 V coils. Up to 1500 Ohms coil resistance. Up to 1 Amp, 20 Watts switching. Suitable for high frequency applications.

102M features a mu-metal case allowing dense packaging without magnetic interaction problems. It has six pins for conventional PCB mounting. With careful PCB layout this configuration will perform well up to 1.5 GHz and will meet most requirements.
