1. The frequency fC is defined as the midpoint between the 3dB frequencies.  
2. Unless noted otherwise, all measurements are made with the filter installed in the specified test fixture that is  
connected to a 50 Ω test system with VSWR1.2:1. The test fixture L and C are adjusted for minimum  
insertion loss at the filter centre frequency, fC. Note that insertion loss, bandwidth, and passband shape are  
dependent on the impedance matching component values and quality.  
3. Unless noted otherwise, specifications apply over the entire specified operating temperature range.  
4. 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 in subsequent years.  
5. Turnover temperature, T0, is the temperature of maximum (or turnover) frequency, f0. The nominal frequency  
at any case temperature, TC, may be calculated from: f = f0 [1 - FTC (T0 - TC)2].  
6. The specifications of this device are based on the test circuit shown above and subject to change or  
obsolescence without notice.  
7. All equipment designs utilizing this product must be approved by the appropriate government agency prior to  
manufacture or sale.  
8. Our liability is only assumed for the Surface Acoustic Wave (SAW) component(s) per se, not for applications,  
processes and circuits implemented within components or assemblies.  
In keeping with our ongoing policy of product evolvement and improvement, the above specification is subject to change without notice.
