Will soldering be an effective method for constructing a microwave resonator?

Click For Summary
SUMMARY

The construction of a TE102 microwave resonator using folded copper sheeting and silver solder is effective for achieving low power leakage and minimal losses. The resonator operates at a frequency of 2.45 GHz and is designed to handle high power levels of approximately 700 watts. Ensuring good physical contact through precise folding and using solder solely for securing the pieces, rather than for electrical connection, is crucial for optimal performance.

So I'm about to construct a TE102 microwave resonator from folded copper sheeting. I'm planning to fold a U shape and join it to the last side with silver solder. Is this going to work well?

I'm planning on making good physical contact through accurate folding, and then securing the pieces with the solder, not use the solder to electrically connect the two.
The resonator operates at 2.45 GHz and will be used at high power ~700watts.

I'm on a limited budget here and am looking for a simple solution that won't leak much power and allow for easy construction.

Thanks

This should work fine. You won't have any leakage, and if the overlapping area is reasonably large, then losses will be low.
