<p>A switch (600) for radio frequency applications includes variable shunt elements and series transmission elements. The impedances of the variable shunt elements and the series transmission elements are selected so that the impedance of the attenuator at the input terminal (IN) remains at a nominal value for all attenuation levels, thereby producing low loss at high frequencies. The use of the switch circuit (601) as an attenuator yields a non-reflective switch at radio frequencies.</p> |
