In datasheet RF1,RF2,RFC,these pin are mentioned as dc-coupled to 0 V and ac matched to 50 Ω. No dc blocking capacitor is necessary when the RF line potential is equal to 0 V dc.
1.Incase these pins are connected with resistive(varies 5Ohms to 1000Ohms) or inductive (Refer Image) load, will RF line potential is equal to 0 V dc or not?
2.Will it affect the channel to channel isolation,If it affected the isolation, how to overcome ( DC blocking capacitor required or not ) ?3.Whether dc blocking capacitor required for cascade (refer image) two or more ADRF5020 ?
