Hello,
I have in my design, a central 6 V supply from a buck converter and this is driving three 5V LDOs. 3 LDOs were selected to isolate the RFICs. LDO2 and LDO3 are powering a modulator and a demodulator respectively and LDO1 provides power to a LNA , and two Amplifiers. Using LDOs I can provide a better PSRR to the RFICs ( rather than driving them direclty from the buck converter). My basic question is when the modulator and demodulator are running, will it create any interference to other devices. Should I keep extra filtering options. Any comments is welcome
