Measuring method of SMA Relays

Measuring method of SMA Relays

With network-analyser you can measure only up to 6 GHz. For higher frequencies you have to use generator and power-meter. This article describes how does the author measure such relays available from various manufacturer such as Narda

SOLID STATE RELAY REQUIRES ONLY 50uA DRIVE CURRENT

SOLID STATE RELAY REQUIRES ONLY 50uA DRIVE CURRENT

This circuit demands a control current that is 100 times smaller than that needed by a typical optically isolated solid state relays. It is ideal for battery-powered systems. Using a combination of a high current TRIAC and a very sensitive low current SCR

5V Capacitance Touch Activated Momentary Switch

5V Capacitance Touch Activated Momentary Switch

It has both a source and sink output that change state whenever a metal button connected to the circuit is touched. An earth ground reference is required.
