<----We've had very good results with the TPRD-1556. Our customers are quite
happy with them. And yes, a good circulator should be mandatory for every

Don't forget that if you add an isolator that you also need a pass band
cavity or low pass filter after the isolator too or you will have a worse
mess than if you did not add the isolator.
