Problems solved by technology

At present, there is a microelectronics institute in China that developed a C-band 2×4-layer space power combining module in December 2007, and the combining efficiency reached 75%. The 4-way spatial power combining network combined with the waveguide-microstrip double-probe transition has a combining efficiency higher than 86% in the Ku band, but the combining is not carried out in the waveguide, and the waveguide power divider / combiner and the waveguide- The volume of the 4-way spatial power combining network combined with the microstrip double-probe transition is large

Embodiment Construction

[0034] Please refer to the accompanying drawings for a further description of the present invention.

[0035] As shown in Figure 1, the double-channel single-sided fin line amplifying circuit board 1 has two parallel microstrip lines 102 on its front side, and a power amplifier chip 101 is arranged on the microstrip line 102; its back side is a double fin line 104, There are flying lead holes 103 on both sides of the microstrip line 102 . The power supply of the two power amplifier chips 101 is respectively on both sides of the microstrip line 102, one of which can be directly powered, and the other can not be directly powered because the power supply terminal is too close to the previous chip. One side of the flying wire method, place the bias circuit on a relatively empty position on the board, use the flying wire to pass through the flying wire hole 103 from the back of the circuit board 1 and solder it to the flying wire hole 103 on the front of the circuit board 1, and am...

Abstract

The invention provides a Ku-band waveguide-based spatial four-way power combiner, which is characterized in that: two pieces of one side finline amplifier PCBs with double channels, which are vertical to an E surface of waveguide, are placed symmetrically in the waveguide as a mode of 2+2; the two pieces of one side finline amplifier PCBs with double channels are isolated by a cushion block so that there is a gap between the two pieces of one side finline amplifier PCBs with double channels. In the invention, four-way power combination is achieved by two pieces of PCBs and the combination is performed in the waveguide, which saves spaces and reduces the volume of the model. Combined efficiency is more than 80%.

Description

technical field [0001] The invention relates to the field of spatial power combining in a waveguide, in particular to a 4-way combining device for combining spatial power in a Ku-band waveguide. Background technique [0002] Nowadays, some military and commercial communication systems require higher and higher output power of high-power solid-state amplifiers. In order to obtain high-power output to meet the needs of these systems, the single power device based on semiconductor technology or vacuum microelectronics technology can be improved. The output power can also use power combining technology to superimpose the output power of multiple solid-state devices in phase to obtain the desired power output. However, from two aspects of cost and reliability, the power combining solid-state amplifier system has obvious advantages. Among the existing power combining categories, compared with chip-level and circuit-level power combining, the advantage of spatial power combining i...
