DL-4x152-FM
General information
The DL-4x152-FM is a four ports 1,5kW FM Termination Load; it is allocated in a custom enclosure specifically designed to be mounted into the back of a standard EIA 19” rack. The working frequency covers the FM range 88-108 Mhz with return loss >30dB. The four 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-4x152-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
