Center Frequency, f0 Insertion Loss at 380 MHz 3 dB Bandwidth Passband Ripple (4) 378.1 - 381.9 MHz Phase Linearity 378 - 382 MHz Relative Attenuation 360 - 373 MHz 387 - 400 MHz Source Impedance: (5) Load Impedance: (5) Notes:
1. 2. 3. 4. 5. All specifications are based on the test circuit shown below In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over temperature Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances Passband ripple is the worst case peak to adjacent valley over a frequency range defined by the measured roll off at the passband edges This is the optimum impedance in order to achieve the performance shown
