The ORPQ series filters are intended for use in test qualification of transmission
pulses used in optical com- munication systems. These filters assist in
determination of compliance to SONET OC eye diagrams. The filters display
close to an ideal Bessel-Thompson transfer function, given by:
H(p) = 1/105 + [105 + 105*y + 45*y2 + 10*y3 +
y4]
with p = j* w/wr
y = 2.114*p
fO = bit rate
The ORPQ series are available with reference frequencies fr ranging
from 50 to 9600 MHz and with a ratio of (fO/fr)=1.33.
Design and construction features an aluminum housing, ceramic substrate
lumped element design for excellent temperature stability.
The filter packages are “in-stock”, allowing fast delivery with low
cost.
Contact factory for other package styles and transfer functions or filter
designs from 1 MHz to 40 GHz, microwatts to megawatts.
