Pasternack Enterprises, an industry-leading manufacturer and supplier of RF and microwave products, expanded their offering of medium and high power RF loads. These RF loads (also referred to as RF terminations and dummy loads) are commonly used in military/aerospace, defense and test and measurement applications in order to protect radios and amplifiers under test from excess power in the system.
The RF terminations from Pasternack come in 25 Watt, 50 Watt and 100 Watt models and are offered with many connector configurations including male and female versions of SMA, N, TNC and 7/16 DIN. The 25 Watt and 50 Watt models operate to 18 GHz, with the exception of the 7/16 DIN version, which is rated to 8 GHz. All of the 100 Watt RF loads operate to 8 GHz. A total of 24 new RF loads are being introduced in this release.
Pasternack’s new medium and high power RF loads are manufactured with black anodized aluminum cooling fins for convection cooling. These coaxial terminations require no additional heatsink to dissipate excessive heat during use. Operating temperatures range from -55 to +125 degrees C, making them an ideal solution for a wide range of environmental conditions in the lab and in the field. The rectangular body can also be hard mounted using 4 threaded mounting holes.
“There are many medium to high power coaxial termination options available, but very few to 18 GHz”, says Gerry Camacho, Vice President of Technical Marketing at Pasternack. “This new offering of medium to high power RF loads provides our customers very broad selections covering wide performance capabilities, allowing them to choose the exact model for the desired application from one supplier.”
