Abstract

A distributed micro-electromechanical system phase shifter chip-level mini-package component relates to a micro-electromechanical system (MEMS) phase shifter chip-level mini-package component. The invention aims to solve problems in a prior bonding approach, such as parasitic effect, strong mutual interference, size and loss increment of a device, occurrence of shape distortion, complicated preparation process and air pollution. A sealing insulation medium package body of the invention is provided with up-down communicated holes; a sealant layer is fixed on an upper surface of the sealing insulation medium package body; the sealing insulation medium package body is made up of polyimide, silicon nitride or silicon dioxide materials; and the thickness (t) of the sealing insulation medium package body is 5-20 Mu m. The invention is operated at 10-50GHz microwave frequency range. And the invention has the advantages of low parasitic effect and mutual interference, good process compatibility, simple process, and small size without shape distortion and air pollution. The insertion loss of the invention is less than -0.2dB, the reflection coefficient is lower than minorq20dB, and the phase shift also has excellent linear relationship.

Description

technical field [0001] The invention relates to a micro-electromechanical system (MEMS) phase shifter chip-level micro-encapsulation component. Background technique [0002] The phase shifter is the most important part of the core components in phased array radar, satellite communication, and mobile communication equipment. Its working frequency band and insertion loss directly affect the anti-interference ability and sensitivity of these equipment, as well as the weight, volume and weight of the system. cost. At present, researchers at home and abroad have developed distributed MEMS phase shifters suitable for millimeter wave miniaturization, low power consumption and low cost. However, the commercialization of distributed MEMS phase shifters is severely hindered because the package structure of distributed MEMS phase shifters cannot provide good mechanical support and environmental protection, superior electrical interconnection and heat dissipation, stable radio frequenc...
