A3RS91.1
High Power Chip Termination
100 Watts
When properly mounted on an appropriate heat sink, this chip
device provides high power dissipation capabilities. Ideal
for ferrite isolator applications, the improved thin film design
technology and laser trimming provide proven RF power
capabilities to meet the demands of today's CDMA and
WCDMA system requirements. Aluminum Nitride is featured
for those applications where the use and disposal of Beryllium
oxide is a concern.
