CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.  
Notes:  
1.  
2.  
Unless noted otherwise, all measurements are made with the filter installed in the specified test fixture which is connected to a 50 Ω test system with VSWR ≤  
1.2:1. The test fixture L and C are adjusted for minimum insertion loss at the filter center frequency, f . Note that insertion loss, bandwidth, and passband shape  
c
are dependent on the impedance matching component values and quality.  
The frequency f is defined as the midpoint between the 3dB frequencies.

Frequency aging is the change in fc with time and is specified at +65°C or less. Aging may exceed the specification for prolonged temperatures above +65°C.  
Typically, aging is greatest the first year after manufacture, decreasing significantly in subsequent years.
