Metal core printed circuit board as substrat for high frequency and microwave circuits

摘要

It is stated, the structure for a circuit board which are particularly suitable as carriers for RF and microwave circuits. On a group consisting of well-conducting material or with highly conductive material (2) coated metal core (1) is a uniform layer coated from a homogeneous vitreous enamel (3). Thereon strip conductors (4) are deposited of copper de-energized. Attenuation values ​​and grades can be resonance for the designed on such a substrate RF and microwave circuits demonstrate that provide values ​​to use today substrates (oxide ceramic, polytetrafluoroethylene) constructed circuits zumidest equal.
