Low loss 360 degree X-band analog phase shifter. |
摘要 |
<p>A low loss reflection-type analog phase shifter circuit producing a large range (nearly 360 DEG ) of phase shift at X-band while achieving low attenuation (insertion loss) and little amplitude variation over all phase states. The results are achieved, in part, by using a terminating impedance which includes parallel-connected hyperabrupt varactor diodes. The circuit is implemented readily in a monolithic microwave integrated circuit using GaAs. <IMAGE></p> |
