5GHz hairpin bandpass on high end fiberglass (Megtron-6)

AI Thread Summary
Experience with distributed element hairpin filters on high-end fiberglass like Panasonic Megtron-6 is limited, with concerns about loss factors affecting Q availability. The discussion highlights the importance of considering moisture absorption and glass weave issues, especially without hermetic sealing. Participants suggest using discrete filters like SAW instead of distributed filters for non-hermetically sealed RF boards. Simulation tools for this type of work are also questioned, indicating a need for proper analysis before implementation. Overall, there is hesitance to pursue this approach due to potential challenges.

Anyone have experience putting distributed element hairpin filter (<5GHz) on high-end fiberglass, such as Panasonic Megtron-6 PCB (vs. Teflon)?
 
Engineering news on Phys.org
Not directly, but look at the Loss Factor for each. It may affect the available Q.
 
No hermetic seal, moisture absorption was one of my concerns. Also concerned about glass weave issues.
Probably not going to attempt it, just curious if anyone out there has been down that road.

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Electromagnet magnetic field issue'

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
