Notes:
(1) Typical values are nominal performances at room temperature.
(2) Q of inductance is supposed to be 40.
(3) The amplitude reference is insertion loss at fo.
(4) Those values greatly depend on customer PCB implantation.
(5) The amplitude variation is defined as the maximum level – minimum level over any 30 MHz block of the given bandwidth.
(6) The phase error is measured over any 30 MHz block of the given bandwidth.
