Patent ID: 7363017

Claim:
A high frequency module including a unit circuit at least having a low noise amplifier for amplifying high frequency signals and a phase shifter IC for adjusting the pass phase of said high frequency signals, said high frequency module comprising: a dielectric substrate having both surfaces thereof metallized, said dielectric substrate having a metallized layer formed on each of both surfaces thereof and having said low noise amplifier and said phase shifter IC mounted on the metallized layer on one surface thereof; a low noise transistor and a distributed constant circuit, formed on said one surface of said dielectric substrate to form said low noise amplifier together; an input terminal, an output terminal and a power supply terminal formed by leading out the metallized layer on said one surface to the opposite side surface of said dielectric substrate by a through-hole in such a manner as to maintain insulation from the metallized layer on said opposite side surface; and a protective material provided for covering at least a circuit component loading surface of said dielectric substrate.
