Latest Patents

Taro Kitayama holds a patent for a "Low distortion switch." This invention aims to realize a high frequency switch with low distortion characteristics. The design features an SPDT switch that consists of multiple FETs. The FET on the receiver side, through which a received signal passes, and the shunt FET on the transmitter side are each formed of series-connected FETs. A capacitor is connected between the first gate and the source, as well as between the second gate and the drain. Additionally, an inductance is connected in parallel with the series connection of FETs. This configuration allows for the realization of a high frequency switch that operates with low voltage and low distortion characteristics. The 1 dB compression level, which is an index of input-output characteristics, can be improved by more than 5 dB over conventional SPDT switches at an input level.
