MRV COMMUNICATIONS, Chatsworth, Calif., sold its majority stake in Luminent's passive components division for about $29 million.
Some researchers and manufacturers want to replace these passive components with tiny machines called microelectro mechanical systems, or MEMS.
One of the main functions of passive components in wireless phones is to filter out all radio frequencies -- including broadcast radio and television signals -- that are outside the band assigned to its system.
Those things do lurk under the keypad, but most of a phone's insides are taken up by filters, duplexers and resonators -- passive components that sort radio frequencies so that you get your calls and not someone else's.
The basic operating principles of the major circuitry and active and passive components used in radio are described in the article electronics.
and even smaller sized passive components.
Passive components are ubiquitous in circuit design.
The passive components are cooled with an air flow.
Both configurations use two OTAs with a few passive components.
This chapter is designed to illustrate various passive components.
Its business includes ceramic passive components, sensorand module, and small size finished.
