Hi all,
One of my observation while integrating the RF circuits in a package as stated below:
All the Rf circuits are fabricated in 10 mil alumina substrate hence the pattern width is ~ 0.25 mm and in few places we have used Isolators having pin width ~0.6mm ( 25 mil approx)( due to non availability of other isolators), all the RF circuits of the package are properly matched to 50 ohm but still i am unable to get a proper gain and output power!, even all the circuits are working properly when tested independently.My doubt goes to the discontinuity due to difference in the width of pattern of microstrip and isolator pin width.Is it ? since each circuit as well as isolators sees 50 ohm, difference in width really creates discontinuity !!! Plz guide me.
Another reason may be all the inter stage connections are carried out by ribbons. Is it a cause of discontinuity !!!
What are the causes of discontinuity ????
Plz guide me to slove the problem
