FIELD: electricity.
SUBSTANCE: hybrid integrated circuit of SHF range representing transmit-receive module of active phased antenna array which has two receiving and one transmitting channels and is made as multilayer card with added components; it is installed and fixed at metal heat-removing base and closed by dielectric cover. Dielectric substrates of multilayer card are made of ceramic, topological metal pattern is made as per thick-film technology; added components included hybrid monolithic circuit of power amplifier and monolithic semiconductor integrated circuits. Microstrip input and output SHF terminals are located at separate thin- film cards and installed at metal heat-removing base in special bays, two terminals at each side of multilayer card. Cover is made bowed and metal plating of shield grounding is applied at its inner surface by thick-film technology while low frequency outputs with contact pads are made at outer surface.
EFFECT: improvement of electrical characteristics and reduction of weigh and dimensions for SHF-range hybrid integrated circuit of APAA transmit-receive module, enhancement of its productibility.
