Notes :
(1) Typical values are nominal performance at room temperature. Minimum and maximum values take into account the variations over
temperature range and the variations of standard matching elements (
± 2% for inductors and ± 5% for capacitors and resistors)
(2) With external matching network.
(3) The amplitude reference is insertion loss at fo.
(4) Ultimate rejection is defined from 400 MHz to 1 GHz
(5) The amplitude variation is defined as the maximum level – minimum level over the given bandwidth.
(6) The nominal value will be confirmed after prototypes delivery.
