DL-3x502-FM
General information
The DL-3x502-FM is a triple 5.0 KW Termination Load; it is allocated in a 3ru height module, suitable to be mounted into a standard EIA 19” rack. The unit includes three 50 Ohm resistive loads, each of them suitable for withstanding separately either an input CW RF Power of 5.0 kW, or a RF Power input simultaneously of 2 kW on each one; the working frequency covers the FM range 88-108 MHz with return loss >30dB. The loads are realized by combining thick film resistors on BeO substrate in order to transfer the heat exclusively by conduction to a suitable heat sink which is than cooled down by forced air. The DL-3x502-FM includes all the mechanical and electronics components in order to achieve the best efficiency and to provide the following functionalities:
- Absorption of the applied RF Power
- System cooling by forced air
- Interlock protection for over temperature and over drive.
