Random Vibration and Shock Tests for Coax Fixed Attenuator
Fixed Attenuators from RF ONE are designed to meet requirements per MIL-DTL-3933. In this report, random vibration and mechanical shock tests are implemented.
Power Coefficient of Fixed Attenuators
Power Coefficient of Fixed Attenuators is a very complicated topic, it is defined as the attenuation change when the attenuator is input with 10mW power and up to its max rated avg power. For example, for a 2W attenuator with a < 0.005 dB/dB/W Power Coefficient, when the input power is increased from 10mW to 2W, then a 30dB attenuator would change in its attenuation by 0.3 dB (30dBx2Wx0.005dB / dB /W).
Flex Life (Bending or Tick Tock) Test for Flexible Cable Assembly
To observe if our test cable UF series (stranded center conductor) will degrade in its insertion loss and VSWR in the highly flex applications and to determine the number of cycles the cable can be bent continuously at a single point before the cable fails, RF ONE has performed the bending (tick tock) test according to standard IEC 60966-1.
Bend-to-the-end Electrical Stability Test of MB260L Cable
MB series from RF ONE is flexible, tight bend cables operating to 50GHz, ideal for high frequency internal interconnection applications. As alternative to Minibend series, it is allowed to bend multiple times just behind the connector with negligible VSWR and insertion loss degradation.
Power Handling of RF Fixed Attenuators
Power handling is a common concern to customers and manufacturers, practically power handling is a complicated topic, because the cause of a device failure from power also depends on the operating conditions such as ambient temperature, heat dissipation, peak power pulse & width etc. RF ONE offers a wide range of low power, medium power and high power attenuators from average 1 W to 2000 W, available in DC to 3 GHz and up to 110 GHz operating frequency ranges.
Temperature Phase Stability Test for RF Cable Assemblies
Phase stability vs. temperature is a measure of the signal speed variation when the cable is exposed to different temperatures. The temperature variation will induce the change of the dielectric constant εr, mechanical length, material character which will cause its phase variation. This variation can be unidirectional or multidirectional.
