Zero-bias bypass switching circuit using mismatched 90 degrees hybrid |
摘要 |
A zero-bias bypass apparatus for a low noise amplifier includes a bypass circuit, and a switching circuit coupled with a low noise amplifier and with the bypass circuit. The switching circuit includes one or more solid state devices responsive to absence of a control bias for switching an RF input signal from said amplifier to the bypass circuit with a low insertion loss and high isolation.
