Abstract

The invention provides a power-up device for a space navigation GaAsMMIC device. The power-up device comprises a positive voltage input end, a negative voltage input end, a positive and negative voltage protection circuit, a temperature compensation grid voltage stabilizing circuit, a drain voltage output end and a grid voltage output end. The positive voltage input end and the negative voltage input end are connected with the drain voltage output end through the positive and negative voltage protection circuit, and the negative voltage input end is connected with the grid voltage output end through the temperature compensation grid voltage stabilizing circuit. The grid voltage output end is used for charging the grid of the GaAsMMIC device. The drain voltage output end is used for charging the drain of the GaAsMMIC device. The positive and negative voltage protection circuit is used for connecting the drain voltage output end to output voltages only when voltages are input into the positive voltage input end and the negative voltage input end simultaneously.

Description

Technical field [0001] The invention relates to the design of a voltage power-up control circuit, in particular to a GaAsMMIC device power-up device for aerospace. Background technique [0002] With the rapid development of military and civilian communication systems such as wireless local area networks, personal mobile communication systems, user direct satellite communications, and global positioning systems, as well as the demand for advanced weapon systems such as active phased array radar, broadband electronic countermeasures, and millimeter-wave precision guidance , GaAsMMIC with high performance and high reliability has developed rapidly. Because GaAsMMIC can meet the requirements for the development of microwave complete system towards multi-function, miniaturization and high reliability; small size, light weight; system functions can be realized on a single chip; no parasitic effects of discrete devices, resulting in excellent frequency and bandwidth performance ; Stand...
