1. An apparatus, comprising:
- a first radio transceiver associated with front-end circuitry operative in a first frequency band;
a second radio transceiver operative in a second frequency band coexistent with the first frequency band, and sharing the front-end circuitry;
a diplexer for effectuating the sharing of the front-end circuitry; and
an antenna connected to the diplexer, and configured to transmit and receive radio frequency (RF) signals for the first and second radio transceivers in the first and second frequency bands.

Abstract
A front-end module and antenna can be shared between two radio transceivers operating in coexistent radio frequency (RF) communication bands. For example, a first of the two radio transceivers may operate in one of a Long Term Evolution (LTE) band or an Industrial Scientific Medical (ISM) band, while a second of the two radio transceivers may operate in an alternative one of the LTE band and the ISM band. Use of a diplexer in the shared front-end module to pass RF signals between the two radio transceivers and the shared antenna can allow for sufficient isolation to avoid interference between transmit and receive operations in the coexistent RF communication bands.

10. A computer program product, embodied on a non-transitory computer-readable medium, comprising:
-
computer code for producing a first RF signal at a first radio transceiver; computer code for receiving a second RF signal from an antenna; computer code for passing the first RF signal to the antenna for transmission, through a front-end module and a diplexer, and passing the second RF signal from the antenna through the diplexer and the front-end module to a second radio transceiver, the front-end module being shared between the first and second radio transceivers, and wherein the transmission of the first RF signal and the receipt of the second RF signal are isolated from each other. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method, comprising:
-
processing a first radio frequency (RF) signal received from an antenna over a first RF band of a plurality of RF bands in which the antenna operates; passing the first RF signal to a first radio transceiver corresponding to the first RF band; receiving a second RF signal from a second radio transceiver corresponding to a second RF band of the plurality of RF bands in which the antenna operates; and processing the second RF signal for transmission through the antenna over the second RF band, the transmission of the second RF signal occurring simultaneously to the receipt of the first RF signal and in accordance with a level of isolation that prevents interference between the receipt of the first RF signal and the transmission of the second RF signal. - View Dependent Claims (19, 20)
