This has reference to subject as above.
Considering: ( -) 60 to 0dBm range of AD8302; ( - ) 30dBm setting requirement at INPB (reference i/p) ) to draw best dynamic range of VMAG i.e. full scale variation (-60dBm to 0dBm) at INPA terminal ; 90 degree phase shift between INPA and INPB to observe complete dynamic o/p swing (30MV to 1.8V) at VPHS; output of DDS (AD9834) as one of the reference input to AD8302 chip.
Question: What should be the ATTENUATORS (INPA and INPB) specifications subject to above considerations to buy from the manufacturer?
I will highly appreciate your intellectual inputs as above.
Thanks and sincere regards,
