I have problem with my 315Mhz SAW
based transmitter if the battery is mounted at
the backside underneath of the transmitter
circuit. It's transmission power will attenuated
at large size around -2dBm down to -40dBm.
Do you have any experience on this problem?
You know it's quite headache, since I been using
many types of battery sheilding material and
ferrite beads, filters caps...still doesn't
Anybody there please help..thanks!
