ABSTRACT:
An orthogonal insertion phase tuning method for easily and efficiently tuning insertion phase without affecting other critical system parameters. The method is used generally with an amplifier network and includes attaching (130) at least two line runners in parallel at the input of the network. The insertion phase is then measured (140) to determine which runner most closely yields an acceptable and desired insertion phase. The remaining line runners are removed (150). An orthogonal relationship exists between insertion phase and input return loss in view of the tuning at a 50 ohm point with 50 ohm runners. This method insures only a minor change to input return loss while quickly and easily adjusting insertion phase.
