Irvine, Calif.—WiSpry Inc. has started to sample MEMS tunable digital capacitors that integrate low power CMOS control and voltage generation logic with an array of tunable RF-MEMS digital capacitors.

The need for what’s called antenna tuning—either by adjusting the antenna itself or via a matching circuit between power-amplifier output and the antenna—is almost as old as wireless itself. Even in ...

HOLLY HILL, FLA., JANUARY 5, 2007: Raptor’s C1FLD 1 farad digital capacitor delivers power, style and attitude to spare. Ready to do the heavy lifting with an 18/26-volt surge working voltage, it also ...

Featuring on-chip capacitors, the ISO721 and ISO721M digital isolators are said to enable faster data transmission with higher signal integrity. Reportedly, the isolators also provide six orders of ...

Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...
