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 RF coaxial reed relays below. These high-frequency reed relays are suitable for up to 5 GHz. Available in through-hole or surface mount.

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.
Series 103G up to 2 GHz
103G & 103GM are 1 Form A relays for up to 20 Watts, 1 Amp with a characteristic impedance of 50 ohms. 3, 5 or 12 V coils. A coaxial electrostatic screen is available.
Ideal for applications where capacitively coupled noise from switch to coil connections is undesirable. Ultra-low capacitance levels of typically 0.1pf from each switch connection to the coil. Also suitable for high frequency applications up to 2GHz.
Series 109RF up to 2 GHz
1 Form A coaxial reed relays with 50- or 75-Ohms impedance. Up to 20 Watts, 1 Amp at 200 V switching. 3, 5 or 12 V coils. Featuring highest quality instrumentation grade switches.
Mu-metal magnetically screened reed relays eliminates problems that would otherwise occur due to magnetic interaction. Insulation resistance greater than 10E12 Ohms (1TOhms). Optional internal diode. Many additional build options available on request.
Series 111RF up to 2.5 GHz
A miniature 50 Ohm coaxial through-hole reed relay suitable for use up to 2.5 GHz. 1 Form A. 5 V coil with optional internal diode. 0.5 Amp, 10 Watts switching.
The coaxial relay is encapsulated in a mu-metal can – to avoid magnetic interaction. Stacks on 0.15 x 0.40 inches pitch, conserving PCB space. Featuring the highest quality instrumentation grade reed switches. 100% tested for dynamic contact resistance.
Series 104ES Reed Relays
These relays can stand-off up to 4kV, switching at up to 25W. There is also an option for an electrostatic shield between the switch and the coil to help minimise noise between the coil drive and high voltage circuits.
