Coaxial Pow er Standar ds 0.1 MHz to 26.5 GHz

(Thermistor Mounts)

FIGURE 1: MODEL F1109

(FEED-THROUGH MOUNT)

TEGAM T emperature Sta bilized Coaxial Po wer Standards
enable precise measurement of microwave power in the

0.1 MHz to 26.5 GHz frequency range. All units are
extremely rugged, highly accurate, stable with time and
temperature, and ideal for use as standards for the
transfer of calibration factors to other standards and
power meters. Units are supplied with calibration data
traceable to NIST with Z540 data standard.

All models are designed for use with dc self balancing
bridges or controllers such as the TEGAM Model 1806
Dual Type IV Power Meter and the Model 1805B RF
Power Level Control Unit. System configurations
employing instruments of this extreme accuracy typically
achieve results in the transfer of calibration factors
normally found only in primary standards laboratories
(refer to System IIA data sheet).

Models F1116, F1119, F1109 and F1117A are Thermistor
Mount/Power Splitter combinations used as feed­through standards for the calibration of terminating
power sensors such as bolometer mounts and po wer meters .

FIGURE 2: MODEL M1110

(TERMINATING MOUNT)

FIGURE 3: MODEL 1807A

(FEED-THROUGH MOUNT WITH CASE)

Models F1119H and F1109H are Thermistor Mount/
Attenuator/Power Splitter combinations used as feed­through standards for the calibration of higher power
terminating sensors. The use of the attenuator/splitter
combination provides a broader band, lower SWR
device . Use of either Model, along with the Model 1805B
and a suitable source of power enables calibration of
1W to 5W terminating sensors directly at a power level
within their normal operating range.

Models M1111, M1120, M1110 and M1118 are
terminating power standards capable of calibration
directly by NIST, and ar e used f or the calibration of feed­through devices such as RF power meters, bolometer
mount-coupler and bolometer mount-splitter assemblies ,
and in other configurations requiring dir ect measurement
of RF power.

CONNECTORS: Mounts feature either Type N or

3.5 mm connectors which mate nondestructively with
SMA, 2.92 mm and other 3.5 mm connectors. Mount
Bias connectors are Binding Posts, standard 0.75"
spacing for Banana plugs.

Models 1807A, F1119C and F1117AC are
feed-through mounts pr ovided with a case
(figure 3) simplifying setup configurations
requiring a precision power standard and
a highly stable RF signal level all in one
package. This package protects the
individual components mounted within
the unit from damage due to mishandling
as can happen with other RF transfer
standards. A pull-out shelf located in the
bottom of the unit is pro vided for use as a
work platform when calibrating power
sensors and power meter mounts or f or the
transfer of calibration factors.

NIST CALIBRATION: Calibration Factors only for the
Models M1110, M1111 and M1118 Terminating Mounts
can be supplied directly by the National Institute of
Standards and Technology.

RACK MOUNTING: Models 1807A, F1119C and
F1117AC are half-rack instruments that can be mounted
in any cabinet or rack designed according to EIA RS-310
and MIL-STD-189 using the Rack Adapter Kit (P/N 1919).
This kit allows any of the models to be mounted with the
model 1805B, or another coaxial power standard in the
same rack-mount configuration.
