Abstract

The invention discloses a power amplifier module with waveguide output. The module comprises a main body, a printed circuit board (PCB), a gold wire, a capacitor, and a single-chip microwave integrated circuit, wherein a channel penetrating the main body, a grounding hole and capacitor mounting holes are formed in the main channel; the PCB is arranged in the channel; an output waveguide is arranged at one end of the channel; the grounding hole is used for the mounting of a grounding assembly; the single-chip microwave integrated circuit is adhered to the PCB, and is connected with an antenna of the PCB through the gold wire; and pins of the capacitor penetrate through the capacitor mounting holes and are connected with a power supply island on the PCB, and the capacitor is used for bypassfiltering of the single-chip microwave integrated circuit. The power amplifier module with the waveguide output has the advantage that the technical problem that connection between an output end of aradio frequency power amplifier and a waveguide-coaxial converter leads to certain loss and an increase of the overall machine cost is solved.

Description

technical field

[0001] The invention relates to the technical field of radio frequency circuits, in particular to a power amplifier module with waveguide output. Background technique

[0002] Most of the RF power amplifier modules are output in coaxial form. This is because the ports of general RF instruments such as network analyzers, spectrum analyzers, power meters, high-frequency signal generators, etc. are output in coaxial form. The coaxial output connectors include N-type connectors, SMA connectors, 2.92mm connectors and 1.85mm connectors.

[0003] But if the working frequency rises to the millimeter wave band, such as the Ka band, the Ka band refers to the frequency band of 26.5-40GHz, which belongs to the millimeter wave band. In order to reduce loss and improve the power capacity of the system, some commonly used modules may use waveguide output. .
