An attenuation cell is provided for use in a switched attenuator. The attenuation cell includes an attenuation path that has an input, a first switch, a resistive network, a second switch, and an output. The resistive network provides a desired attenuation from the input to the output. The attenuation cell also includes a bypass path in parallel with the attenuation path with a bypass switch between the input and the output. The attenuation cell also has a shunt switch coupled between the resistive network and a reference node to selectively connect the resistive network to the reference node.

A Wilkinson power divider includes: -type LPFs connected to an input terminal; a T-type HPF having one end connected to one of the -type LPFs and having another end connected to a carrier amplifier; another T-type HPF having one end connected to another one of the -type LPFs and having another end connected to a /4 line; and an isolation resistor connected to connection points.
