Model 640105 Air Cooled-ALTRONIC RESEARCH

Model 640105 Air Cooled

The 6400 Series air dielectric coaxial loads deliver the same high performance of the 6700 Series in a smaller package. The 6400 Series was designed to operate using static or forced air while exhibiting stable RF characteristics. The small, compact oil free design is a welcome advantage in a busy transmitter area. Applications run from mounting on top of the transmitter to placing them inside the cabinet. Model 640105 is an excellent load for VHF transmitters with separate inputs for the aural and visual ports.

How To Measure Your Bust

With your arms relaxed at your sides, measure around the fullest part of your chest.

How To Measure Your Waist

Measure around the narrowest part of your natural waist, generally around the belly button. To ensure a comfortable fit, keep one finger between the measuring tape and your body.

RF Load Types

• RF load designs are determined by impedance, power

handling capability, cooling method, and frequency range:

→ Power handling capability: 1-watt, 10-20 watt, 100-300 watt,

or many kilowatts

→ Impedance is typically 50 ohms unless otherwise stated

→ Quality of match can vary from good (typical for “loads”) to

excellent (typical for precision “terminations”)

→ Cooling method could be ambient air, forced air, closed-system oil

conduction to air fins, forced water, etc. it depends on the

power levels involved

→ A “broadband” RF load will represent a 50-ohm match with low VSWR

over a specified frequency range, but some loads are designed to be

a good match at only one frequency
