Abstract: The use of RF connector in integrated circuit is wide.However，the complexity of the interface of the RF connector determines the degree of difficulty of manufacturing the housing that contains RF insulators.In this article，the development of a microwave sealing housing that contains feeder insulators and RF insulators is introduced.Given the structure characteristics and technique requirements of this product，it discards the old unitary manufacturing processes，integrates the craft characteristics of sintering and soldering，uses hybrid manufacture techniques，and solves the issues regarding the moulding design and processing.Through testing，the results below regarding the RF insulators in this sealing housing are found，VSWR is less than 1.2@40 GHz，insertion loss is equal to or less than 0.7 dB，leakage rate is equal to or less than 1×10-3Pa·cm3/s.
