BPF 900/9
Interdigital Band-Pass Filter for the 900 MHz Band
DESCRIPTION
The BPF 900/9 is a 9-resonator, interdigital band-pass filter for
multichannel systems in the 900 MHz band.
Using interdigital principles the following features are obtained at the
same time:
Wide Pass Range
Low insertion loss and ripple inside pass range
Steep slopes immediately outside pass range
Heavy attenuation outside the pass range.
The BPF 900/9 housing is made of silvered brass. Careful design and
choice of materials ensure a long lifetime and reliable operation over a
wide temperature range.
The filter can be delivered with centre frequency between 880 and
960 MHz. The specifications and the curves below refer to a filter with
35 MHz port width, but interdigital filters with other port widths and
filter characteristics may be quoted on request.
