Operate the driving voltage with the high-side switch (Vcont_1 & Vcont_2, not ground). 2. It is necessary to discharge the charge that accumulates in the electrostatic actuator to turn off the RF MEMS Switch because this product is a MEMS Switch of an electrostatic drive type. Install the electrical discharge circuit in the drive circuit of the RF MEMS Switch with a resistance of 1 M or less. Without an electrical discharge circuit, the RF MEMS Switch might not turn off, and the contacts could stick.

Connect EACH RF ground pad to the internal RF ground plane through the via placed to the RF ground pad. *RF Ground Pad is designated as Safety Precautions Precautions for Correct Use * Turn off power when doing the exchange and the wiring work of the RF MEMS Switch. * Do not touch the terminal of the RF MEMS Switch when energized. RF MEMS Switch Handling * Use the RF MEMS Switch as soon as possible after opening the moisture-proof package (within one week). If the RF MEMS Switch is left for a long time after opening the moisture-proof package, the appearance may suffer and seal failure may occur after the solder mounting process. To store the RF MEMS Switch after opening the moisture-proof package, place it into the original package and seal the package with adhesive tape. * When washing the product after soldering the RF MEMS Switch to a print circuit board, use a water-based solvent or alcohol-based solvent and keep the solvent temperature to less than 40C. Do not put the RF MEMS Switch in a cold cleaning bath immediately after soldering. * Do not use an Ultrasonic wash. * This RF MEMS Switch is easily damaged by static electricity. When handling the RF MEMS Switch, take countermeasure against static electricity (100 V or less). Contact OMRON for additional guidelines. * When handling the RF MEMS Switch, do not drop. * Do not apply force resulting in the product to transform and change in quality. Long-term, Continuous ON Contacts * Using the RF MEMS Switch in a circuit where the RF MEMS Switch will be ON continuously for long periods (more than 24 hours) (rather than switching) can lead to unstable contacts. If a singleside stable model must be used in this kind of circuit, we recommend adding fail-safe circuits in case the contact fails. Claw Securing Force During Automatic Mounting * During automatic insertion of RF MEMS Switches, be sure to set the securing force of each claw to the following so that the RF MEMS Switch's characteristics will be maintained. Direction C: 2.0 N max. Environmental Conditions for Usage, Storage, and Transport * Avoid direct sunlight when using, storing, or transporting the RF MEMS Switch and maintain normal temperature, humidity, and pressure conditions. * Avoid caustic gases when using, storing, or transporting the RF MEMS Switch. Coating * Do not coat the RF MEMS Switch when it is mounted to the print circuit board. Do not wash the print circuit board after the RF MEMS Switch is mounted using detergent containing silicone. Otherwise, the detergent may remain on the surface of the RF MEMS Switch.
