Balance Port<br />
λ/4 Resonator<br />
Main electric characteristics<br />
-Balance Impedance<br />
-Insertion loss at pass b<strong>and</strong><br />
-Phase balance<br />
-Amplitude balance<br />
・the length of strip line decide frequency<br />
・dielectric constant material can make resonator shorter<br />
・coupling of λ/4 resonator decide b<strong>and</strong>width<br />
