Coaxial RF / High Speed Digital Reed Relays

All Pickering reed relays feature the highest quality instrumentation grade reed switches making them suitable for the most demanding applications. Internal mu-metal magnetic screens (optional on Series 103) allow very high packing density. Diodes are optional.

Pickering Series 102

Subminiature Coaxical RF Reed Relays

SoftCenter™ construction
• Highest quality instrumentation grade reed switches
• Form A (energize to make) or Form B (energize to break) configurations
• Many benefits compared to industry standard relays. Learn more here >.
• Up to 20 watts switching capability
• Insulation resistance greater than 10E12 Ohms (1TOhms)
• 5, and 12 Volt coils are standard, with or without internal diode
• 100% tested for dynamic contact resistance

The Series 102 is a range of subminiature coaxial reed relays for high frequency applications up to 3 GHz. Two package types are available, both displaying outstanding RF performance in terms of low insertion loss, good isolation and excellent VSWR characteristics in 50 ohms systems.

These relays have good coil drive levels making them ideal for portable applications or where space is at a premium. If an even smaller RF relay is required, look at the Series 109RF or 111RF.

102M (Mu-metal) Package.
This device, constructed in the popular Single-In-Line format, features a mu-metal case allowing dense packaging without magnetic interaction problems. It has six pins for conventional PCB mounting. With careful printed circuit board layout this configuration will perform well up to 1.5 GHz, it is easy to use and will meet most requirements.

102F (Flatpack) package.
The 102F package dispenses with the leadframe connections to the switch and screen. These terminations are instead brought out axially from the ends of the device where they are soldered directly to the stripline. This
technique allows very accurate matching to the 50 ohms line and gives an excellent VSWR right up to 3 GHz.

Mounting method:
A small rectangular hole is punched into the printed circuit board or notched into the board edge to accommodate the package. The switch leads are then soldered directly to the 50 ohms stripline, the tin plated copper foil from the screen is soldered directly to the ground plane on the reverse side of the P.C.B. The coil connections are soldered directly to their tracks in the same way.
