NOTES:
1. Under pulse RF operating conditions.
2. These devices are designed for RF operation. The total device dissipation rating applies only when the devices are operated as pulsed RF
amplifiers.
3. Thermal Resistance is determined under specified RF operating conditions by infrared measurement techniques. (Worst case θJC value
measured @32 µs, 2.0%)
Preferred devices are Motorola recommended choices for future use and best overall value.
