Probe-Station Test Cables Perform Through 70 GHz
RF coaxial cable/connector maker MegaPhase is featuring a new line of high-frequency probe-station test cables, dubbed the MegaPhase PS Series.
The PS Series test cables address dynamic probe station measurements, offering low-loss, phase-stable performance through 70 GHz. The cables can be mechanically formed to help ensure proper connector-to -connector spacing and that interfering surfaces associated with a given probe can be avoided while facilitating the station head’s complete freedom of movement.
The PS Series probe station cables include:
>> Phase/amplitude stable for greater measurement accuracy
>> Low VSWR: Better than 1.45:1 at 40 GHz and 50 GHz; 1.50:1 at 67 GHz
>> Insertion loss: Better than 4.26 dB at 40 GHz; 6.00 dB at 50 GHz; 6.85 dB at 67 GHz
>> Shielding effectiveness: Greater than 90 dB per MIL-STD 1344, Method 3008
connectors
>> 26.5 GHz: Precision SMA
>> 34 GHz: 3.5 mm connector- intermateable with SMA, 2.9-mm interfaces
>> 40 GHz: 2.92-mm ("K" type) – intermateable with SMA, 3.5-mm interfaces
>> 50 GHz: 2.4-mm – intermateable with 2.4-mm and 1.85-mm interfaces
>> 67 GHz: 1.85-mm – intermateable with 2.4-mm and 1.85-mm interfaces
Custom lengths available upon request for all frequencies, and they are sold as both OEM components or as replacement cables for existing probe stations. Samples and production quantities are available.
