HSCH-9161
Description
Agilent’s HSCH-9161 detector
diode is a beamlead, GaAs device
fabricated using the modified
barrier integrated diode (MBID)
process
[1]
. This diode is designed
for zero bias detecting applica-
tions at frequencies through
110 GHz. It can be mounted in
ceramic microstrip (MIC), finline
and coplanar waveguide circuits.
Applications
At room temperature and frequen-
cies under 10 GHz, the silicon zero
bias Schottky detectors
HSMS-0005 and HSMS-2850 offer
comparable performance. How-
ever, the HSCH-9161 yields
virtually flat detection sensitivity
from 10 to 30 GHz with good
performance from 30 to 110 GHz.
In a wideband matched detector,
in which a shunt 50
resistor is
used in front of the diode, voltage
sensitivity (
γ
) is calculated to be
1 mV/
μ
W. Where a high-Q reactive
impedance matching network is
substituted for the shunt 50
resistor, values of
γ
approaching
25 mV/
μ
W can be expected.
In applications below 10 GHz
where DC bias is not available and
where temperature sensitivity is a
design consideration, the HSCH-
9161 offers superior stability when
compared to silicon zero bias
Schottky diodes.
