Abstract

The invention discloses a Ku band solid state power amplifier, comprising heat dissipation systems, amplifier modules, a control and detection module, a six-way power divider and a power module. An output end of the six-way power divider is connected with six groups of amplifier modules. Power-on and protection of the amplifier modules are controlled by the control and detection module. Heat dissipation systems are set at two sides of the whole of the amplifier modules and the control and detection module. The heat dissipation systems, the amplifier modules, the control and detection module and the six-way power divider are connected with the power module. According to the design, bare chips are employed, so a structure is compact and beautiful; a sink form is employed for a link, so the disassembly and maintenance are convenient; and through combination of gallium arsenide chips and gallium nitride chips, an amplifier assembly has relatively good linearity and more has relatively highefficiency. The design plays a role in the fields such as a radar simulation device and electronic countermeasure.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a Ku-band solid-state power amplifier. Background technique [0002] As an important part of the active array antenna, solid-state power amplifier components have developed rapidly since the 1970s. With the increasing technical indicators of microwave power transistors, the output power and operating frequency of solid-state power amplifiers are also moving towards high-power and high-frequency bands. Expand. For solid-state amplifier transmitters, in order to obtain the power output of thousands of watts or even tens of kilowatts, we usually use the method of power synthesis. There are two specific methods: one is to use power synthesis technology based on circuits or waveguides, and the second method It is a method of using an active array antenna, which is based on free space power combining technology, and obtains high power output by using space power combi...
