For this reason I was looking at the HMC877LC3 but I would like to keep the design simple.
I am interested to something more like HMC247 since it is very easy and simple, but I would like to avoid using wire bonding to connect it.
I found two phase shifters working at high frequency:HMC247 and HMC877LC3.
I would then like to ask you:
- is it possible to bias the HMC877LC3 by connecting the VDCP input only?
- can the inputs and outputs be used in a single-ended configuration?
- the evaluation PCB has SMAs to the bias inputs. It there a specific reason for that?
