Abstract
An RF switch for an RF splitter is disclosed, in which the bias voltage for the RF switching elements can be supplied, by using an RF to DC translator, from the RF signal on the input side to the switch. By using a native NMOS switch, routing of the RF signal is thus enabled without the necessity for an external power supply.
Claims7
An RF switch comprising:
- an input;
- an output;
- a switching element, wherein the switching element has a threshold voltage of substantially zero;
- a loop-through channel having an amplifier which is configured to be bypassed by the RF Switch;
- and
- a Radio Frequency (RF) to Direct Current (DC) converter electrically connected to the input, configured to supply a bias voltage to the switching element which is greater than the threshold voltage, and configured to operate without an external power supply by receiving power from the loop-through channel.
