We are using HMC1118 & ADRF5040 to build a 24x1 MUX and on the input and output of the MUX we are using HMC1118s for better isolation. Can we connect RF1 or RF2 of HMC1118 directly to GND or we need to put capacitor in between?
Unused RF port of the HMC1118 can be connected to ground through a 50ohm resistor. There is no need to use dc blocking cap as the HMC1118 has 0Vdc bias on RF ports.
