Abstract
One embodiment of the present invention provides a multi-band RF transmitter. The RF transmitter includes an RF integrated circuit (IC) chip that includes a plurality of identical wideband ports for outputting modulated RF signals, a plurality of narrowband power amplifiers (PAs), and a plurality of matching networks. A respective narrowband power amplifier (PA) is coupled to a wideband port of the RF IC chip via a respective matching network.
Claims11
A multi-band RF transmitter, comprising:
- an RF integrated circuit (IC) chip that includes a plurality of identical wideband ports for output modulated RF signals;
- and
- a plurality of amplification branches, wherein a respective amplification branch includes a narrowband power amplifier (PA) and a corresponding matching network, and wherein the RF IC chip is configured in such a way that the respective amplification branch can be coupled to any wideband port on the RF IC chip.
An interface device for interfacing between an antenna and a transmitter RF IC chip having a plurality of identical wideband ports, comprising:
- a plurality of amplification branches and a reconfigurable multiplexer, wherein a respective amplification branch includes a narrowband power amplifier (PA) and a corresponding matching network, and wherein the amplification branch can be configured to couple to any wideband port on the transmitter RF IC chip regardless of an operating frequency band associated with the narrowband PA of the amplification branch.
