Embodiment Construction

[0048] figure 1 An example embodiment of a Doherty amplifier circuit 100 is shown. The Doherty amplifier 100 has a Doherty input 102 and a Doherty output 104 . Splitter 106 , main power amplifier 112 and peaking power amplifier 114 are connected between Doherty input 102 and Doherty output 104 , among others. As will be discussed in detail below, each of these components 106 , 112 , 114 is advantageously provided by means of an integrated circuit 126 .

[0049] Some components of the Doherty amplifier circuit 100 are implemented on an integrated circuit (IC) 126 and some components are implemented on a laminate. This results in a compact solution. Together, the laminate and IC 126 may be considered part of the same Doherty amplifier device. Accordingly, the components of the Doherty amplifier circuit 100 may be distributed between the IC 126 and a laminate-based PA module (eg, a two-layer laminate). Distributing the design between the chip and the laminate can be an econo...

Abstract

The invention discloses a Doherty amplifier circuit. The Doherty amplifier circuit comprises: a splitter having: a splitter-input-terminal for receiving an input signal; a main-splitter-output-terminal; and a peaking-splitter-output-terminal; a main-power-amplifier having a main-power-input-terminal and a main-power-output-terminal, wherein; the main-power-input-terminal is connected to the main-splitter-output-terminal; and the main-power-output-terminal is configured to provide a main-power-amplifier-output-signal; a peaking-power-amplifier having a peaking-power-input-terminal and a peaking-power-output-terminal, wherein: the peaking-power-input-terminal is connected to the peaking-splitter-output-terminal; and the peaking-power-output-terminal is configured to provide a peaking-power-amplifier-output-signal. The splitter, the main-power-amplifier and the peaking-power-amplifier are provided by means of an integrated circuit.

Description

technical field [0001] The present invention relates to Doherty amplifier circuits, and in particular, to Doherty amplifier circuits that may be implemented at least in part as integrated circuits. Background technique [0002] With the development of wireless infrastructure, more and more heterogeneous networks are utilized to meet the demands of global high data rate services. Small cells are deployed to enhance capacity in the network by increasing the re-use of spectrum on a denser network mesh. This will allow power stages up to 4W peak per small cell PA. Therefore, it is desirable to take advantage of the integration capabilities of the BiCMOS process. Contents of the invention [0003] According to a first aspect of the present invention, there is provided a Doherty amplifier circuit, the Doherty amplifier circuit comprising: [0004] a splitter having: [0005] a splitter input for receiving an input signal; [0006] main splitter output; and [0007] Peak sp...
