Booth N818 Altronic Research now offers oil-cooled RF dummy loads. While providing better RF characteristics than what has previously been available, these loads also have better RF stability under full power. The dummy loads use Power Film Systems’ low TCR proprietary resistors along with higher performing cooling dielectric oil.
The 1100 Digital Series oilcooled RF loads operate in the 470–890 MHz range. The five models cover the range from 1 to 10 kW and all feature 50 ohm inputs, 1.1:1 or less VSWR.
