Pickering Series 102

Subminiature Coaxical RF Reed Relays

SoftCenter ® construction
• Highest quality instrumentation grade switches
• Form A (energize to make) or Form B (energize to break) configurations
• 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 portableapplications or where space is at a premium. If an even smaller RF relay is required, look at the Series 109RF or 111 RF.

Pickering Series 103

Low Capacitance SIL Reed Relays
For stacking on 0.2 inches pitch

SoftCenter ® construction
• Highest quality instrumentation grade switches
• Inter-terminal capacitances are a fraction of that for standard SIL relays
• Pin compatible with standard 0.2 inch SIL relays
• Optional internal mu-metal magnetic screen
• Optional internal coaxial electrostatic screen
• Insulation resistance greater than 10E12 Ohms (1TOhms)
• 100% tested for dynamic contact resistance

The Pickering Series 103 is a range of Single-in-Line reed relays intended for such applications as wide bandwidth A.T.E. switching matrices, attenuator switching or any other applications where exceptionally low levels of inter-terminal capacitances are required, for example, when carrying fast rise time pulses.

Pickering Series 109

Micro-SIL Reed Relays - Including coaxial types for stacking on 0.15 x 0.6 inches pitch giving SUPERB PACKING DENSITY

SoftCenter ® construction
• Highest quality instrumentation grade switches
• 1 Form A (energise to make)
• 2 Form A (energise to make)
• 1 Form C (change over)
• 1 Form B (energise to break)
• 1 Form A Coaxial 50 Ohms impedance (energise to make)
• 1 Form A Coaxial 75 Ohms impedance (energise to make)
• Insulation resistance greater than 10E12 Ohms (1TOhms)
• 5 and12 Volt coils are standard, with or without internal diode

The mu-metal packaged Series 109 and 109RF and the plastic packaged Series 109P and Series 109PH, are magnetically screened single-in-line reed relays that stack on 0.15 inches x 0.6 inches pitch. The adjacent column gives further details of the device types available.

These relays require little more than half the board area of themore usual 0.2 x 0.8 inch devices, this allows around 80 percent more relays onto your board.

These are the ideal choice for high density applications such as A.T.E. switching matrices or where very little board area is available.

Pickering Series 111

PICO SIL Reed Relays
Including coaxial types for up to 1.5 GHz for stacking on 0.15 x 0.4 inches pitch giving SUPERB PACKING DENSITY

SoftCenter ® construction
• Highest quality instrumentation grade switches
• Mu-metal magnetic screening
• Internal mu-metal magnetic screen
• Two package styles - Mu-metal package or Plastic package with internal mu-metal magnetic screen
• They take up the minimum of board area,conserving
board space
• Insulation resistance greater than 10E12 Ohms (1TOhms)
• 5 Volt coils with or without internal diode
• 100% tested for dynamic contact resistance

The Pickering Series 111 is a range of magnetically screened single-in-line reed relays that stack on 0.15 inches by 0.4 inches pitch. They have an identical footprint to the Series 110 and 112 but the height is reduced to only 0.26 inches (6.6mm).

The switch rating of 3 Watts is adequate for most instrumentation applications. If a higher power rating is required, please look at our Series 110 or 112 which have a 10 Watts rating and an identical pin-out. The range also includes the type 111RF, a 50 ohms coaxial device suitable for use up to 1.5 GHz.

Pickering Series 200

Surface Mount Reed Relays
Including coaxical types for up to 5GHz

SoftCenter ® construction
• Highest quality instrumentation grade switches
• Encapsulated in plastic package with internal mu-metal screen for side-by-side mounting without magnetic interaction
• Insulation resistance greater than 10E12 Ohms (1TOhms) for Form A devices
• For R.F. or high speed digital applications, 50 or 75 ohms coaxial devices are available in the same small package
• Wide range of switch configurations - 1 Form A, 1 Form B, 2 Form A. 1 Form C
• Dry and mercury wetted switches available
• 5 and 12 Volt coils are standard, with or without internal diode
• 100% tested for dynamic contact resistance

The Series 200 is a complete range of surface mount reed relays.Both dry and mercury wetted switches are available in a wide range of configurations including coaxial types for RF up to 5GHz, or high speed digital switching with a step response time of less than 30ps. Please contact our technical department for
supplementary RF data.

The special high temperature plastic package will withstand the temperatures associated with Infra-red or vapour phase reflow soldering processess. A flexible inner encapsulant protects the sensitive glass/metal reed switch seals - this is a very big advantage over the more usual hard moulded package.

Pickering Series 99

RF Reed Relays - HF Switching

• Non-coaxial reed relays with copper plated switches for low insertion loss
• Low capacitance from switch to coil
• Air filled for low dielectric loss
• Ideal for transmit / receive filter selection in frequency agile transceiver
