Abstract

The invention provides a microwave device cavity, a microwave device and an antenna. The microwave device cavity is suitable for installing a circuit board with a microwave circuit, and comprises an inner cavity, two opposite side walls of the inner cavity are provided with a first neck and a second neck, the first neck and the second neck face each other, the circuit board can be inserted into the first neck and the second neck, and the first neck is higher than the second neck, so that the lower plane of the first neck supports the back side of a pad. The first neck and a second neck are formed in the side wall of the inner cavity; a circuit board can be inserted into the inner cavity; for a thin circuit board, the heights of the first neck and the second neck are larger than the thickness of the circuit board, the first neck and the second neck are arranged in an up-down staggered mode, the lower plane of the first neck makes contact with the circuit board, the back side of the bonding pad of the circuit board is supported, and therefore the stability of the circuit board is improved when a cable is welded in a microwave device.

Description

technical field

[0001] The invention relates to the technical field of mobile communication, in particular to a microwave device cavity, a microwave device and an antenna. Background technique

[0002] At present, the cost pressure of base station antennas continues to increase, but the requirements for product stability are also increasing, and providing a low-cost and high-stability antenna has become a mainstream development trend. Among them, reducing the total cost of antenna products by reducing the thickness of the circuit board inside the phase shifter is one of the more common solutions, and the thickness of the circuit board can be reduced to 0.2mm. However, because the cavity generally adopts the production method of pultrusion, a circuit board slot with a thickness of 0.2 mm cannot be formed in the cavity. When the circuit board is inserted into the circuit board slot, due to the difference in thickness between the circuit board and the slot Matching, there is a...
