RF Impedance Tuner Circuit Design

[ttkane]

how can i design impedance tuner locate smith chart anywhere .
In addition to use Coaxial Line Stretcher module.

because my company did not have stretcher. so i hope it can achieve by circuit.


thanks

A line strecher puts in a physical delay, but is wideband, so the phase shift will increase as the frequency increases, but amplitude wise it is lossless. An impedance tuner will only work over a restricted bandwidth. So if you let us know what centre frequency you want and what sort of characteristics you want, perhaps some one here can help you.

Thanks For your reply,
my centre frequency is 2.4G and 5G.

it's any sort of circuit are no required.
