I would like to know whether the digital attenuator HMC424ALP3E requires a linear power input or works fine with a switching power input?
What is the best power input for HMC424ALP3E ?
Thanks in advance!
The HMC424ALP3E requires negative supply and control voltages of -5V. If you have only positive supply voltage available in your system, you will need to use a switching regulator to generate negative supply voltage. If you already have negative supply voltage different than -5V, you can use a linear regulator just to adjust supply voltage to -5V.
