Variable Attenuators
HP 382A Series
The attenuation value of these direct-reading, precision attenuators depends on the rotation angle of
the resistive card, rather than on the resistivity value of the attenuating material. Therefore, they are
insensitive to changes in temperature and humidity which can affect the resistive card of ordinary
adjustable flap attenuators. The attenuation value is highly accurate and is stable from 0 to 50 dB.
The instruments feature large, easy-to-read dials, and can handle considerable microwave power.

Directional Couplers
HP 752 Series
The HP 752 series couplers are an essential part of many
microwave measurement applications. Attenuation
measurements, reflectometer setups, power measurements, source leveling and network analysis are just a
few areas in which directional couplers find use.
HP's X, P, K, and R band couplers have a conventional
multi-hole design featuring greater than 40 dB
directivities. The HP R752CS,DS and Q, U, V, W 752C,D
couplers are designed with "split-block" technology, and
provide greater than 33 dB directivity. Split-block
designs are used to assure
greater precision in machining the ultra-small internal
dimensions required by the 26.5 to 110.0 GHz waveguide.
The split block units are equipped to interface with
the precision circular cover flanges with matching
alignment pins common to those applications.
Each coupler is swept-frequency tested to ensure that
the main guide SWR and directivity specifications are
accurate. Performance characteristics are unaffected
by humidity, temperature and time. This makes these
units especially useful in microwave "standards"
measurements.

HP 365A Series
These products are ideal isolators for test and measurement applications.
Their high, broadband isolation (better than 25 dB) minimizes the
reflection effects of a source. Their low SWR and low insertion loss help
to improve accuracy without the attenuation of matching pads.
The HP 365A isolators use a Faraday-rotation design. It consists of a
waveguide section that contains low-loss ferrite material and impedance
matching elements. A permanent magnet supplies the external magnetic
bias field to the ferrite core.

Terminations, Fixed and Sliding
HP 910 Series Fixed Terminations
HP 910 waveguide loads are designed for terminating
test systems operating at low average powers. The
loads are carefully designed to absorb virtually all
of the applied power and ensure a lower SWR. They
may be used wherever a matched load is required,
as in the measurements of reflection, discontinuities,
or obstacles in waveguide systems.
HP X914B Sliding Load
This sliding load consists of a movable, tapered, lowreflection load element mounted in a section of precision
waveguide. A plunger controls the position of the load,
and provides a controllable range of at least one-half
wavelength at the lowest waveguide frequency. This
movement permits the phase of the residual load
reflection to be reversed so that this reflection can be
separated from other small reflections in the waveguide
system. Sliding loads are often used in calibration
procedures.
