Power inserter having frequency compensating function

A power inserter having frequency compensating function, comprising:

• a housing formed with a chamber, a first opening, a second opening and a third opening;
• a first connector exposed outside said housing through said first opening;
• a second connector exposed outside said housing through said second opening;
• a third connector exposed outside said housing through said third opening;
• a first capacitor having a first terminal coupled to a signal terminal of said first connector and having a second terminal coupled to the ground potential;
• a first coil having a first terminal coupled to said first terminal of said first capacitor;
• a second capacitor having a first terminal coupled to a second terminal of said first coil and having a second terminal coupled to the ground potential;
• and
• a second coil having a first terminal coupled to said second terminal of said first coil and having a second terminal coupled to a signal terminal of said third connector;
• characterized in that:
• a third capacitor being further provided, a first terminal of said third capacitor being formed with a winding having at least half turn and coupled to said signal terminal of said third connector, a second terminal of said third capacitor being formed with a winding having at least half turn and coupled to a signal terminal of said second connector, thereby being enabled to provide the frequency compensating function.
