balanced
(2) fo is the real center frequency of the filter and the specified template is centered at this frequency (average value of
the 2 measurements at -14 dB and -15 dB). Due to the material, Lithium Tantalate, the frequency shift versus the
temperature variation is given by : fo(
θ) – fo(θo) = - KTa (θ - θo) fo(θo) with KTa = 18 ppm/°C
