2 to 18 GHz SM Bandpass Filters
Part numbers B028RF2S to B148QF0S
Description
Utilizing DLI’s high permittivity, NP0 ceramics allow for small
size, temperature stable performance over frequency and
high reliability in environmentally challenging conditions. This
series of bandpass filters was designed to span the popular
2-18 GHz frequency range. The compact size and surface
mount attachment allow for low cost of manufacturing
without sacrificing performance and repeatability. Designed
for use on PCB 8-12 mils thick with a permittivity of 3.0-3.8.
Features
