All specifications are based on the test circuit shown below 2. This specification is valid for room temperature only 3. Device will function over an operating temperature of -40 to 85 oC, but may not meet the above ambient specification. Insertion loss and frequency shift performance will change over temperature. See coefficient of temperature for frequency shift estimation. 4. Electrical margin has been built into the design to account for the variations due to manufacturing tolerances 5. Referenced to insertion loss at 479.75 MHz 6. Referenced to 100% of 1dB bandwidth 7. This is the optimum impedance in order to achieve the performance shown Test Circuit: Actual matching values may vary due to PCB layout and parasitics 50 Ω Single-ended 1,2,4,5,6,7 8,10,11,12 50Ω 12pF 50Ω39pF Subject to change or obsolescence without notice Rev A 25-Jul-2003 Page 2 of 5
