Hi
what is the difference between RF-circuit board ( high frequency ) and
non-RF-circuit board ?
What happen when I use non-RF-circuit board for 900 MHz frequency ?

Thanks

Fero

The differance is the material the copper is on. It can cause the tuned
circuits to be differant and it may be so lossey the material will burn if
the power is high enough.
