Abstract
A low-loss Radio Frequency (RF) switch for high-power RF signals. The RF switch includes a first-biasing circuit connected to a first transistor and a second-biasing circuit connected to a second transistor. The RF switch switches its output signal between a first input signal and a second input signal. The first transistor is in a conduction state and the second transistor is in a non-conduction state when the first input signal is to be conducted to the output signal. The first-biasing circuit biases the first transistor at a first voltage for increasing conduction of the first input signal and the second-biasing circuit biases the second transistor at a second voltage for decreasing conduction of the first input signal. Moreover, the second transistor is in a conduction state and the first transistor is in a non-conduction state when the second input signal is to be conducted to the output signal.
