Coaxial/RF/High Speed Digital Dry Reed Series 103 switch ratings - The contact ratings for each switch type are shown below: Switch No Dry Relays - Data and type numbers Config No Magnetic screen or Guard screen Magnetic screen only Guard screen only Guard screen and Magnetic screen Switch form Form A A A A A A A A A A A A A A Switch Power rating 1 A 15 W 1.0 A 1.2 A 200 10E9 0.5 ms 0.2 ms General purpose 2 A 10 W 0.5 A 1.2 A 200 10E9 0.5 ms 0.2 ms Low level Switch no.2 is particularly good for switching low currents and/or voltages. It is the ideal switch for A.T.E. systems where cold switching techniques are often used. Where higher power levels are involved, switch no.1 is more suitable.

For example, for an ‘end of life’ contact resistance specification of 1 Ω, switching low loads (10 V at 10 mA resistive) or when ‘cold’ switching, typical life is approx 1 x 10 9 ops. At the maximum load (resistive), typical life is 1 x 10 7 ops. In the event of abusive conditions, e.g. high currents due to capacitive inrushes, this figure reduces considerably. Pickering will be pleased to perform life testing with any particular load condition. Note 2 Capacitance across open switch The capacitance across the open switch was measured with other connections guarded. Simplified equivalent circuits It is convenient to consider the internal capacitances as a delta network as in the circuit diagram alongside. C1 is the capacitance between one end of the switch and the coil, C2 is the capacitance between the other end of the switch and the coil. These two figures will be approximately equal. C3 is the capacitance across the open switch. When measuring the values of any one of these capacitances, it is necessary to “guard” the unused relay connections to avoid the parallel effects of the other capacitances, connection details when performing these measurements on a capacitance bridge are shown below. Relays with an internal electrostatic screen have the screen terminals guarded in all cases. Measurement of C1- switch to coil Bridge Measuring Terminals Bridge Guard Terminal Max. switching volts Life expectancy ops typical (see Note 1 below) Measurement of C2- switch to coil Bridge Guard Terminal Bridge Measuring Terminals Operate time inc bounce (max) Release time Special features Standard operating temperature range: -20 to +85 °C. Note: The upper temperature limit can be extended to +125 °C if the coil drive voltage is increased to accommodate the resistance/temperature coefficient of the copper coil winding. This is approximately 0.4% per °C. This means that at 125 °C the coil drive voltage will need to be increased by approximately 40 x 0.4 =16% to maintain the required magnetic drive level.

Coaxial/RF/High Speed Digital Pickering Series 102 Subminiature Coaxial SIL/SIP Reed Relays for RF and High Speed Digital Up to 20 Watts switching Features • SoftCenter ® construction (see adjacent diagram) • 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 10 12 Ω • 3, 5 and 12 Volt coils with or without internal diode • 100% tested for dynamic contact resistance for guaranteed performance The Series 102 is a range of subminiature coaxial reed relays for high frequency applications up to 3 GHz, performance characteristics will be found on reverse of this sheet. 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 111 RF. 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 1.5GHz, 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.
