Abstract
Systems, apparatuses and methods are disclosed providing signal conditioning circuits configured to condition RF signals, and an interface in communication with the signal-conditioning circuits, the interface including M inputs and N outputs, each of the quantities M and N greater than 1. The interface is configured so that each of at least two of the M inputs is coupled to a separate output through a separate switch.
Claims14
A radio-frequency module comprising:
- a single-pole, multiple-throw switch coupled at a pole to an antenna signal transmission path and at each of a quantity M of throws to a separate one of M signal paths configured to transmit radio-frequency signals;
- and
- an interface module including M input pins electrically coupled to the M signal paths, respectively, and a quantity N of output pins, each of the quantities M and N greater than 1, the interface module including a first signal path connected between a first input pin of the M input pins and a first output pin of the N output pins via a first single-pole single-throw switch, a second signal path connected to a second input pin of the M input pins and including a second single-pole single-throw switch, and a third signal path connected to a third input pin of the M input pins and including a third single-pole single-throw switch, the second and third single-pole single-throw switches being associated with hardware-programmable wire-bonding, such that the second and third signal paths can be selectively coupled together to a second output pin of the N output pins within the interface using the hardware-programmable wire-bonding.
A wireless device comprising:
- a circuit board;
- a transceiver mounted on the circuit board and configured to process radio-frequency signals;
- a radio-frequency module mounted on the circuit board in communication with the transceiver, the radio-frequency module including a quantity M of signal paths configured to transmit the radio-frequency signals, the radio-frequency module further including an interface module including M input pins and M output pins, the interface configured so that each of the M input pins is coupled to a separate output pin of the M output pins through a separate single-pole single-throw switch;
- M conductive traces on the circuit board, each electrically coupled to a respective one of the M output pins of the interface module, at least two of the M conductive traces being combined together on the circuit board to thereby provide on-board consolidation of radio-frequency signal paths;
- and
- an antenna in communication with the radio-frequency module, the antenna configured to receive the radio-frequency signals.
