GENERAL INFORMATION
These high power devices are designed to dissipate power in RF
circuits when mounted to an appropriate heat sink. The termina-
tions provide a low VSWR under maximum power conditions. The
resistor configurations are typically used in “Wilkinson” type power
divider networks, or to terminate 3 dB stripline or microstrip hybrids.
Aluminum nitride is used for those applications where the use and
disposal of beryllium oxide is a concern.

RESISTORS & TERMINATIONS
High Power, Aluminum Nitride, Thin Film, Drop-in – 10-600 Watts, DC-4 GHz
NOTES
1. Input power ratings are based on flange
temperature of 100° C maximum.
2. 50 and 100 Ohms standard. Other values
from 10-500 Ohms available on special order.
Contact factory for details. Standard tolerance ±5%.
Specify resistance value when ordering.
3. VSWR applies to termination style only.
