S -BAND LOAD ISOLATORS
S10 series of S -band Microwave Load
Isolators provides higher isolation with
1/3 less space and weight. Engineered
for min. size and weight, a wide variety
of Litton isolators in the S10 series
CONNECTORS
These Amphenol Micro -Ribbon connectors,
utilizing an improved version
of the amphenol- developed "ribbon"
contact design, have been developed for
miniaturization programs. Amphenol
CHASSIS KIT
New 3 -D Chassis Kit provides complete
flexibility in the construction of
prototype models. Low -cost construction
kit consists of: end brackets, side
channels, terminal strips, miniature and
offers reverse attenuation of 10 to 30 db
or higher, with corresponding insertion
losses of 0.5 to 1.5 db. The new S -band
isolators can handle 500 kw. peak
power and 250 w. average without external
cooling. With air or liquid cooling,
power handling capacity can be
increased substantially. Litton Industries,

OUTPUT STANDARDIZER
This new subminiature decade capacitor
(silver mica) switch provides capacitance
values from 10 mmfd to 9990
mmfd ( ±1 %) that is variable in discrete
switch steps of 10 mmfd. The primary
design use is for standardizing the
voltage output from Endevco self -generating
pressure, force, and acceleration
pickups to one value of output voltage.

VARIABLE DELAY LINE
This delay line is capable of providing
continuously variable delay from 0
to 1 µsec. and more. The amount of
equalization has been made exactly
equal to its correct optimum value. Rise
time less than 8% of the time delay at
any point, no overshoot, excellent stability,
hairline accuracy, and complete
freedom of time jitter. The size is only
1 in. x 6 in. x 6 in. Three different
models are available. The useful band-
