Abstract
A switchable reactance unit includes an RF terminal configured to connect to a transmission line for transmitting a signal at a frequency in a range of 1-200 MHz, and a switching arrangement comprising a plurality of switching elements used in parallel. Each switching element has a control terminal, and is connected to the RF terminal via at least one individual reactance assigned to the switching element and connected in series with the switching element. The switching elements are controllable or controlled via their control terminals in such a way that they switch simultaneously.
Claims21
A switchable reactance unit comprising:
- a radio frequency (RF) terminal configured to connect to a transmission line for transmitting a signal at a frequency in a range of 1-200 MHz, and
- a switching arrangement comprising a plurality of switching elements used in parallel, each switching element having a control terminal, and being connected to the RF terminal via at least one individual reactance assigned to the switching element and connected in series with the switching element, wherein the control terminals of the plurality of switching elements being are connected to one another and thereby are controllable in such a way that the plurality of switching elements are switched on or off simultaneously with switching differences less than or equal to 100 ns.
A variable reactance comprising a switchable reactance unit that comprises:
- an RF terminal configured to connect to a transmission line for transmitting a signal at a frequency in a range of 1-200 MHz, and
- a switching arrangement comprising a plurality of switching elements used in parallel, each switching element having a control terminal, and being connected to the RF terminal via at least one individual reactance assigned to the switching element and connected in series with the switching element, wherein the control terminals of the plurality of switching elements are connected to one another and thereby are controllable in such a way that the plurality of switching elements are switched on or off simultaneously with switching differences less than or equal to 100 ns.
