General Description
856691 is a 1.5MHz bandwidth filter which is part of
TriQuint’s 140MHz center frequency family for use in IF
filtering for various channelized communication systems.
Housed in a hermetic surface mount package, 856691
offers low insertion loss, constant group delay, and good
input power handling capability.
856691 offers an excellent choice for narrowband selection
for communication systems.

Notes:
1. All specifications are based on the TriQuint schematic for the main reference design shown on pages 3 and 5
2. In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over
temperature
3. Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances
4. Typical values are based on average measurements at room temperature
5. Relative to minimum insertion loss
6. This is the optimum impedance in order to achieve the performance shown
