Abstract
An improved distributed amplifier (200) includes an input transmission line (201) terminated with an input lead configured to accept an input signal and an output transmission line (202) terminated with an output lead configured to output an output signal. A number of parallel amplifier cells (204N) are connected to the input transmission line (201) and the output transmission line (202) that collectively amplify the input signal from the input lead to produce an amplified output signal at the output lead. A bypass switch (212, 300) is connected to the input and output transmission lines (201, 202). The bypass switch (212, 300) is operative to convert either the input transmission line (201, 301) or the output transmission line (202, 302) into a bypass line configured to bypass the parallel amplifier cells (204N) of the distributed amplifier (200) and provide a direct path between the input and output transmission lines (201, 202) to produce a bypassed output signal at the output lead.
