Abstract: One design aspect in electronic systems, such as communication systems, is noise suppression. More particularly, this relates to microphonics suppression in high-speed communication systems, such as microwave wireless radio systems. The present invention contemplates system design for substantially eliminating microphonic behavior created by mechanical stimulus such as vibrations and the drum effect. A preferred approach includes isolating the motherboard from its mounting harnesses (mechanical interconnection) and adding an echo damping and shock absorption pad to the underside of the enclosure cover to stiffen the enclosure cover while maintaining its light weight. Preferably also, this approach isolates the entire motherboard rather than a particular component. A design using this approach is particularly useful in an outdoor unit (ODU) of a split-mount microwave radio system.

Abstract: Waveguide flanges for joining waveguide sections or components are designed to achieve mechanical strength and exhibit desired electrical properties such as relatively low insertion loss and high return loss. The present invention contemplates waveguide interfaces with a new choke flange designed to engage with a shield flange and provide a joint with improved electrical properties. The new choke designs produce a virtual continuity through the waveguide joints and minimize electrical energy leakage. The electrical and mechanical properties of the joint in the waveguide interfaces are robust and able to tolerate lower levels of parts precision, imperfect mating of the flanges without metal-to-metal contact and gaps up to 0.06? or more between the mating flange surfaces.
