High Power, Thin Film, Drop-in – 10-650 Watts, DC-4 GHz
GENERAL INFORMATION
These high power devices are designed to dissipate power in
RF circuits when mounted to an appropriate heat sink. The ter-
minations provide a low VSWR under maximum power condi-
tions. The resistor configurations are typically used in
“Wilkinson” type power divider networks, or to terminate 3 dB
stripline or microstrip hybrids.
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.
