Menlo micro

Solidstate Switches redefined:
From mW to kW, from DC to GHz

Compared to electromechanical relays, reed relays and high power relays Menlo Microsystems offers MEMS-Technology based Switches with improved reliability and features. Menlo Microsystems is a spin-off company from GE and now represented by Eurocomp Elektronik GmbH. The principe of the MEMS-Switch is shown in the attached figure. Type MM3100 e.g. a RF-tuning device, is housed in a 6 x 6 mm QFN. The 6 channel switch for DC to 3 GHz operates at 5 V and draws only 1 mA for switching. On-resistance is only 10 mOhm, very low compared with the 200 mOhm of the solid state relays SSR. Other important features are the insulation voltage of 2500 V, switching frequency up to 10 kHz and no derating up to 85 °C.

Additional MEMS Switches for highest frequencies are MM7100 (HV-switch, SPST, 2 A, DC to 750 MHz, 400 V, 2 A housed in 5 x 5 mm LCC) and MM5120 (RF-switch, SPDT, DC to 12 GHz W housed in 5 x 5 mm QFN).

Menlo Microsystems MEMS Switches target the market for relays in general, which is still dominated up to more than 50 % by electromechanical versions. Due to the improved features MEMS-Switches from Menlo Micro can be used as a replacement for all kinds of switches including PIN-Diodes, solid states relays, circuit breakers etc.
