Notes:
1.
Unless noted otherwise, all specifications apply
over the operating temperature range
with filter soldered to the specified
demonstration board and measured with 50
network analyzer. Center frequency is defined as: ( f
3dB HIGH
- f
3dB LOW
) / 2.
Unless noted otherwise, all frequency specifications are referenced to the nominal center frequency, fc.
Rejection is measured as attenuation below the minimum IL point in the passband. Rejection in final user application is dependent
on PCB layout and external impedance matching design. See Application Note No. 42 for details. Spurious responses may exceed
ultimate rejection specification at fc x1.6 and above.
Quality factor, Q, is defined as: Q
3dB
= fc / ( f
3dB HIGH
- f
3dB LOW
).
Amplitude variation is defined as the difference between the insertion loss at the baud frequency and filter’s minimum insertion loss.
Transmission phase slope is measured in the frequency domain and is calculated using a linear least-squares fit or straight-line
method over the 3 dB bandwidth.
Phase deviation from linear is specified over the 3 dB bandwidth. It is defined as the maximum residual deviation of the
transmission phase from linear least-square fit over the 3 dB bandwidth.
The design, manufacturing process, and specifications of this filter are subject to change.
Either Port 1 or Port 2 may be used for either input or output in the design.
