Description
・極低消費電力:静電気作動は、きわめて低い電力消費(開閉サイクルあたり10〜100nJ)のため、いかなる電流も消費しない。
・極高絶縁:RF MEMS直列スイッチは、エアギャップを有して製作されて、したがって、0.1〜40GHzで優れた絶縁に結びつく極低オフ状態キャパシタンス(2〜4fF)を有する。
・極低挿入損失:RF MEMS直列分流器スイッチは、最高40GHzまで0.1dBの挿入損失を有する。
・相互変調製品:MEMSスイッチは、非常に線形のデバイスであり、したがって、極低相互変調製品に結びつく。それらの性能は、ピン(p−i−n)またはFETスイッチよりも約30dB良好である。
・極低コスト:RF MEMSスイッチは、表面(またはバルク状)マイクロマシン加工技術を使用して製作されて、そして、水晶、パイレックス(登録商標)、低温コファイアード・セラミック(low temperature cofired ceramic;LTCC)、メカニカルグレード高抵抗率シリコン(mechanical−grade high−resistivity silicon)、またはガリウム砒素基板上に構築されることができる。
・RF回路構成−直列または並列。
・機械構造−片持ち構造またはエアブリッジ構造。
・接触形態−容量性(金属−絶縁体−金属)抵抗性(金属−金属)。
