Durable, precision Coaxial Transmission Line Test Adapters-
provide superior electrical performance and reliable service in engineering development, troubleshooting evaluation and production test applications.
Ruggedly constructed from gold-plated beryllium copper and stainless steel, these 50 Ohm adapters are well suited for use in laboratories as well as production and field environments where more fragile adapters do not hold up. They exhibit long-term stability of electrical performance, and provide low attenuation and VSWR, resulting in more accurate measurements.

Testing
Each Test Adapter is tested to verify VSWR performance over the Test Frequency Range.
Typical Adapter Configuration Part Number: TMTA/SMAF/TKF
ORDERING INFORMATION
A complete Part Number is specified as follows:
TMTA/C1/C2
Where C1 = Interface 1 Designator
C2 = Interface 2 Designator
NOTE that Interface Designators are to be placed in alphanumeric sequence.
(This eliminates redundancies in part number control and stocking.)
Example 1 – SMA female to TK female adapter part number is TMTA/SMAF/TKF
Example 2 - TNC male to N female adapter part number is TMTA/NF/TNCM
Example 3 - TNC female to 3.5mm male adapter part number is TMTA/TNCF/3.5M
