Similar performance can be achieved in source and load impedances ranging from 50 to 1000 ohms. (2) The typical insertion loss may vary slightly depending on actual source and load impedances, matching configuration and PC board layout. (3) Inductors with 2% tolerance may be required. (4) In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over temperature.
