Hi all,
for one of my RF project, I have to provide 5 volts supply to RF transceiver module witch operates in 868MHz, due to space constraints i have go for resistor to step down the 230 volts power supply to 5 volts(without using transformer) and convert to DC 5/3.3 volts by using rectifier.
1. can i go for the resistor option to step down 230volt to power up the RF board? if yes any precaution need to be taken care?
2. is there any other option available to power up the RF board without using transformer.
3. is there will be any 50Hz leakage interference to the RF performance?
Pls suggest for any precaution or for bets option for my above issues.
Thanks.....:-(
