Intermodulation Distortion (IMD)
|
Intermodulation Distortion (IMD) level testing was performed using an HP 8568B Spectrum Analyzer with a full 1,500w out, at 14.100 MHz, with a 2 KHz carrier separation. IMD testing was performed in Denver, Colorado in August of 2015 in a controlled lab.3rd order IMD:-33.5 dB (1,500w Carrier)
-39.5 dB (1,500w PEP) |
Thermal Design and Inter-Chassis Airflow
|
Amplifier Board Cooling
PA cooling design has been optimized to provide maximum airflow directly at the FETs and heat spreader cooling fins, followed by an immediate exhaust path by way of our custom designed wide exhaust duct near the center of the amplifier chassis. Our heat spreader consists of a block of Alloy #110 copper with 99.9% purity, custom CNC’d for our PA board with .400″ thickness, interfacing with an extruded aluminum fin block.
Power Supply Cooling
The 3 kW switch mode power supply (SMPS) employs its own independent, temperature-controlled cooling system utilizing (2) fans. We have designed separate power supply intake & exhaust ducting which allows cold, non-contaminated air to reach the SMPS intake on one side of the amplifier, and hot exhaust air to exit the chassis on the opposite side. The power supply ducting was designed to accommodate either side or bottom intake & exhaust paths, or both.
