Description
本発明は、インピーダンス整合に関し、特にそれに限定されるわけではないが、電力増幅器のインピーダンス整合に関する。
本発明の分野においては、電力増幅器のような装置から、エネルギの最適転送のため、電力増幅器の出力インピーダンスは、その電力増幅器により駆動される回路の入力インピーダンスと整合すべきであることが知られている。実際には、集積回路(IC)電力増幅器(PA)のような電力増幅器の出力インピーダンスは、通常、当該ICに対して外部に取り付けられ且つ当該ICにワイヤにより接続されているインダクタ及びキャパシタのような構成要素を含む電気的/電子的回路網の使用により整合される。ワイヤ・ボンディングは、通常、ワイヤを接続するため用いられる。キャパシタは、金属酸化物半導体キャパシタ(MOSCAP)又は表面取り付けデバイス(SMD)型キャパシタであり得る。インダクタは、一般的に、前述のキャパシタにより正確な位置で接地に分路(シャント)されるマイクロストリップ又はコプレーナ線路のような伝送線を用いて作られる。
[発明の概要]
本発明は、添付の特許請求の範囲に記載されたインピーダンス整合のためのモジュールを提供する。
最初に図1を参照して、電力増幅器102(例えば、セルラ無線応用に使用のモジュール・デュアル・バンド(2バンド)PAのようなもの)のための既知のインピーダンス整合装置100は、ある一定数のワイヤ104を有し、そのある一定数のワイヤ104は、整合されるべきRF電力トランジスタ108を有するIC106とプリントされた伝送線(以下、「プリント伝送線」という。)110との間に従来のワイヤ・ボンディング技術により取り付けられている。外部の表面取り付けデバイス(SMD)キャパシタ112が、アース/接地と、ワイヤ104から遠く離れたプリント伝送線110上の正確な位置との間に接続される。
・実現が容易
・整合の精度が増大
・少ししか外部の構成要素を必要としない
・製造が容易
・専用の設計フローを必要としない
・標準のIC生産及び試験ツールだけしか必要でない
・低損失の整合回路網を使用
・(キャパシタの統合化のため)ダイの大きさが少しだけ増大するが、しかし本解決策の合計の大きさは、外部の構成要素の数が低減するので、著しく(例えば、50%)低減し得る。
