Abstract

The invention relates to a radio module configured to accommodate multiple bands in a telecommunication terminal. The radio module comprises: a power amplifier module (1) with an antenna port (2) connectable to an antenna, and an input port connectable to a transmitter section of a transceiver (11); a reception front end module (8) connectable to the antenna port and a reception section of a transceiver; wherein said power amplifier module and said front end module are capable of covering a number of frequency and/or modulation bands through said antenna port.

Claims

1. A multiband radio module comprising:

a power amplifier module with an antenna port connectable to an antenna, and an input port connectable to a transmitter section of a transceiver;

a reception front end module connectable to the antenna port and a reception section of a transceiver;

wherein said power amplifier module and said front end module are capable of covering a number of frequency and/or modulation bands through said antenna port.

2. A multiband radio module according to claim 1, wherein the power amplifier module comprises at least two transmission branches with filters and power amplifiers for low and high frequencies, respectively.

3. A multiband radio module according to claim 2, wherein the input port of the power amplifier module comprises a number of filters and switch means for controlling which band is transmitted from the transceiver.

4. A multiband radio module according to claim 1, wherein the front end module comprises at least two branches with filters for low and high frequencies, respectively.

5. A multiband radio module according to claim 4, wherein the front end module comprises a number of filters and switch means for controlling which band is transmitted to the transceiver.

6. A telecommunication device, comprising a radio module with:

a power amplifier module with an antenna port connectable to an antenna, and an input port connectable to a transmitter section of a transceiver;

a reception front end module connectable to the antenna port and a reception section of a transceiver;

wherein said power amplifier module and said front end module are capable of covering a number of frequency and/or modulation bands through said antenna port.

7. A telecommunication device according to claim 6, wherein the device is a portable telephone, a pager, a communicator, a smart phone, or an electronic organiser or a PC card.
