Abstract

The invention belongs to the technical field of matrix switches, and particularly relates to a 4 x 4 full-switching matrix switch based on a single-pole four-throw switch. The switch comprises substrates, TSV through holes, signal line networks and ground wire units. The number of the substrates is four, the signal line networks and the ground wire units are arranged on the substrates, and the ground wire units are arranged on the two sides of the signal line networks. The four substrates are bonded in sequence through a bonding material. The matrix switch is mainly formed by cascading four groups of single-pole four-throw switches through the TSV through holes, and has the characteristics of simple structure, small size, low straight-through insertion loss, rapid multi-channel transmission and the like; from the perspective of microwave transmission, the signal interference of a single branch is improved, and the transmission performance among the branches of the switch is improved; and moreover, quick switching of four paths of signals can be carried out in a working frequency range, the practicability is relatively high, and the efficient communication requirement of the satellite can be met. The switch is used for gating switching of microwave signals.

Description

technical field [0001] The invention belongs to the technical field of matrix switches, and in particular relates to a 4×4 full switching matrix switch based on a single-pole four-throw switch. Background technique [0002] In communication satellites, multiple received signals are simultaneously transmitted to designated transmission outputs with high sensitivity through a high-order switch matrix. Microwave or millimeter wave switch matrices provide comprehensive signal transmission for satellite communication systems. The switch matrices used so far are based on mechanical switches. Mechanical switches are reliable, have low losses, and can drive high power with high linearity. However, they are slow, bulky, heavy, and require motors for switching, which are very unsuitable for the miniaturization of communication satellites. [0003] RF MEMS-based switch matrices offer several advantages in space applications compared to those based on mechanical or solid-state switch...
