Description
ELVA-1 YIG-tuned bandpass filters cover octave and
multi-octave frequency band from 1 to 37.5 GHz. These YIG
filters offer excellent tuning linearity, good frequency
stability, excellent selectivity and off-resonance rejection.
YIG filters with 3 dB bandwidths ranging from very narrow 0.1%
from Central frequency to wide bandwidths up to 4%. Dual
channel configurations of YIF filters with several MHz
matching between channels are also available to order.
We supply YIG filters as components only, or assembled with
Analog (0-10V) / Digital (12-bit TTL) drivers. Please keep in
mind that in first case you need very stable current source to
control YIG filter.
Basic YIG filter products are 4stage filters, which have
selectivity of 24dB/octave from 3dB BW. BWXXdB at
isolation level xxdB can be calculated as:
BWXXdB = BW3dB * [(xx (3+Insertion
Loss))dB/24dB]
When you order YIG filter, please advise following terminology
for YIG filters, that are represented on Fig. 1 below.

We produce YIG filters on request, based on products line
represented in Table 1 below. Before order, please contact us to
advise required parameters.
