Abstract
An RF switch arrangement includes a shunt switch having a first RF terminal, a second RF terminal coupled to ground, a main control input, and an acceleration control input; a series switch having a first RF terminal coupled to the first RF terminal of the shunt switch, a second RF terminal, a main control input, and an acceleration control input; and a switching time acceleration circuit having a positive acceleration path input, a negative acceleration path input, and a first output coupled to the main control input of the series switch.

An RF switch arrangement comprising:
- a shunt switch having a first RF terminal, a second RF terminal coupled to ground, a main control input, and an acceleration control input;
- a series switch having a first RF terminal coupled to the first RF terminal of the shunt switch, a second RF terminal, a main control input, and an acceleration control input;
- and
- a switching time acceleration circuit having a positive acceleration path input, a negative acceleration path input, and a first output coupled to the main control input of the series switch.
An RF switch arrangement comprising:
- a shunt switch having a first RF terminal, a second RF terminal coupled to ground, a main control input, a main control output, an acceleration control input, and an acceleration control output;
- a series switch having a first RF terminal coupled to the first RF terminal of the shunt switch, a second RF terminal, a main control input, and an acceleration control input;
- and
- a shunt-series switch coupled between the main control output of the shunt switch and the main control input of the series switch, and coupled between the acceleration control output of the shunt switch and the acceleration control input of the series switch.
A method of operating an RF switch arrangement, wherein the RF switch arrangement comprises a series switch including a first switching time acceleration circuit, a shunt switch including a second switching time acceleration circuit, and a shunt-series switch for selectively coupling the series switch to the shunt switch, the method comprising:
- establishing a conductive path during a switching transient and an OFF-state operational mode of the series switch;
- and
- breaking the conductive path during an ON-state operational mode of the series switch.
