Observe precautions for handling. Notes: 1. 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. 2. Unless noted otherwise, all measurements are made with the filter installed in the specified test fixture, which is connected to a 50Ω test system with VSWR ≤ 1.2:1. The test fixture’s L and C are adjusted for minimum insertion loss at the filter center frequency, fC. Note that insertion loss, bandwidth, and passband shape are dependent on the impedance matching component values and quality. The optimum impedance matching component values are dependent on circuit parasitic losses. 3. The frequency fC is defined as the midpoint between the 3dB frequencies. 4. Unless noted otherwise, specifications apply over the entire specified operating temperature range. 5. One or more of the following U.S. Patents apply: 4,454,488; 4,616,197; and others pending. 6. All equipment designs utilizing this product must be approved by the appropriate government agency prior to manufacture or sale. 7. The design, manufacturing process, and specifications of this device are subject to change without notice. 8. The turnover temperature, TO, is the temperature of maximum (or turnover) frequency, fO. The nominal center frequency at any case temperature, TC, may be calculated from: f = fO [1 - FTC (TO -TC)2]. RF Monolithics, Inc.
