Discussion on High Power Attenuator Failure and Prevention Guide
Through our dozens of years of market feedback and technical experience, we have observed that failures in RF coaxial fixed attenuators predominantly occur in the ≥200 W( CW) power range. The vast majority of these failures manifest as burnt-out internal resistor elements. This article is to address causes of failure, failure symptoms, and preventive countermeasures, also we have elaborated why it is important to monitor the case temperature.
Analysis Report for Flexible Cable Flexing Life
RF ONE has conducted a thorough test and analyzing in order to systematically verify the bending life of RF ONE’s different series of microwave flexible cables and provide product selection guidance.
Salt Spray Test for Fixed Attenuators and Terminations
In order to evaluate the metal materials and its protective coatings used for RF ONE Coax Fixed Attenuators and Terminations are able to withstand the accelerated corrosion test, we have performed the salt spray test accoding to method 101 of MIL-STD-202 on 8 type of our terminations and attenuators made of passviated stainless steel.
Coaxial Switch Terminology
The three most common switch types are (1) single-pole-double-throw (SPDT), (2) Transfer (DPDT), and (3) multiposition.
Cryogenic Performance of RF ONE Microwave Products
At RF ONE, we often receive inquiries from customers about the feasibility of using our microwave products in cryogenic applications. We would like to share the actual data to demonstrate that our 27GHz SMA 2W attenuator functions well at cryogenic temperatures.
Cable Thermal Shock Test
We perform thermal shock in accordance with method 107 of MIL-STD-202.
The purpose of this test is to determine the resistance of our Flexible RF Cable Assemblies to the exposures at high and low temperatures and to the shock of alternate exposures to these extreme temperatures.
