Abstract
A front end module includes an antenna port, two or more bandpass filters forming a signal path with the antenna port, each of the bandpass filters having a different passband, one or more amplifiers, the one or more amplifiers being disposed between the two or more bandpass filters and the antenna port in the signal path, and one or more switches configured to connect one of the two or more bandpass filters to the one or more amplifiers. A corresponding wireless device and wireless access point are also provided.
Claims20
A front end module comprising:
- an antenna port;
- two or more bandpass filters forming a signal path with the antenna port, each of the bandpass filters having a different passband;
- one or more amplifiers, the one or more amplifiers being disposed between the two or more bandpass filters and the antenna port in the signal path;
- and
- one or more switches configured to connect one of the two or more bandpass filters to the one or more amplifiers, the one or more switches including a first switch coupled to the one or more amplifiers and directly coupled to the antenna port.
A front end module comprising:
- an antenna port;
- two or more bandpass filters forming a signal path with the antenna port, each of the bandpass filters having a different passband;
- one or more amplifiers, the one or more amplifiers being disposed between the two or more bandpass filters and the antenna port in the signal path, the one or more amplifiers including a first amplifier disposed between the antenna port and the two or more bandpass filters, and a second amplifier disposed between the antenna port and the two or more bandpass filters;
- and
- one or more switches configured to connect one of the two or more bandpass filters to the one or more amplifiers, the one or more switches including a first switch coupled to the one or more amplifiers and directly coupled to the antenna port, the one or more switches further including a second switch coupled to the one or more amplifiers and to a third switch, the third switch being coupled to the two or more bandpass filters, a fourth switch and a fifth switch, the fourth switch being coupled to the fifth switch and to the two or more bandpass filters, and the fifth switch further being coupled to at least one transmit node and at least one receive node.
A wireless device comprising:
- one or more antennae;
- and
- one or more front end modules, each front end module having an antenna port connected to one of the one or more antennae;
- two or more bandpass filters forming a signal path with the antenna port, each of the bandpass filters having a different passband;
- one or more amplifiers, the one or more amplifiers being disposed between the two or more bandpass filters and the antenna port in the signal path;
- and
- one or more switches configured to connect one of the two or more bandpass filters to the one or more amplifiers, the one or more switches including a first switch coupled to the one or more amplifiers and coupled directly to the antenna port.
