FRONT END MODULE WITH SWITCHABLE FILTER

Abstract:

A front end module for a wireless device. The front end module comprises an input port to receive a first radio frequency signal, a power amplifier, an antenna port, a first transmit/receive path, a second transmit/receive path, a switch, and a switching circuit. The power amplifier is coupled to the input port and configured to amplify the first radio frequency signal. The antenna port provides the amplified first radio frequency signal to an antenna. The first transmit/receive path includes a filter, and the switch includes a first contact coupled to the first transmit/receive path, a second contact coupled to the second transmit/receive path, and a third contact coupled to the antenna port. The switching circuit is configured to selectively couple the power amplifier to the antenna port via one of the first transmit/receive path and the second transmit/receive path.
