Abstract
A front end module having transmit loopback functionality may be operated by conducting a loopback signal from an output of a power amplifier to a receive port on a transmit loopback path and conducting a radio frequency receive signal from an antenna port to the receive port on a receive path. The transmit loopback path includes a first switch coupled between the output of the power amplifier and the receive port. The receive path includes a second switch coupled between the antenna port, where the receive port and is without the first switch.
