Scalable radio frequency switch matrix for multiport signal routing

A method, comprising:

• electrically coupling, by a system comprising at least one processor, a first radio frequency (RF) port of an RF switch matrix to one or more selectable RF ports other than the first RF port, wherein the first RF port is electrically coupled to the one or more selectable RF ports via mechanical micro-actuator-based switch sets, the mechanical micro-actuator-based switch sets comprising groups of unit cell switch matrixes between the first RF port and the one or more selectable RF ports, and connection switches between unit cell switch matrixes of the groups of unit cell switch matrixes, the electrically coupling comprising:
• determining which of the one or more selectable RF ports to electrically couple to the first RF port;
• for each selectable RF port determined to be one to electrically couple to the first RF port,
• controlling first ones of the unit cell switch matrixes corresponding to the selectable RF port, in conjunction with controlling at least one of the connection switches between the first ones of the unit cell switch matrixes corresponding to the selectable RF port, to be in actuated states that electrically couple the selectable RF port to the first port;
• and
• for each selectable RF port determined not to be one to electrically couple to the first RF port,
• controlling second ones of the unit cell switch matrixes corresponding to the selectable RF port to be in de-actuated states that electrically decouple the selectable RF port from the first port.

A radio frequency (RF) switch matrix, comprising:

• RF ports;
• respective unit cell switch matrix devices, the respective unit cell switch matrix devices comprising respective groups of mechanical micro-actuator-based switches coupled to the RF ports;
• and
• respective connector switches coupled between the respective unit cell switch matrix devices,
• wherein application of first respective voltages selectively controlled by at least one controller determines a first operational state of a first RF switch matrix of the respective unit cell switch matrix devices, corresponding to a first subgroup of respective mechanical micro-actuator-based switches controlled to be in first actuated states, and a second subgroup of respective mechanical micro-actuator-based switches controlled to be in first de-actuated states,
• wherein application of second respective voltages selectively controlled by the at least one controller determines a second operational state of a second RF switch matrix of the respective unit cell switch matrix devices, corresponding to a third subgroup of the respective mechanical micro-actuator-based switches controlled to be in second actuated states, and a fourth subgroup of respective mechanical micro-actuator-based switches controlled to be in second de-actuated states,
• wherein application of third respective voltages selectively controlled by the at least one controller determines a third operational state of the respective connector switches, and
• wherein the third operational state of the respective connector switches, in conjunction with the first operational state and the second operational state, couples a first input port of the respective sets of RF ports to an eighth RF port of the RF ports.
