High-frequency amplifier switching in wireless devices
Installation & Usage Notes:
-
Surface-mount onto PCB; since PCB design and heat dissipation conditions affect contact carrying power, verification under actual operating conditions is required
-
Heat sink required for high-power (150 W) operation at 2 GHz
-
When using in applications with low-level loads or high-frequency switching, consult the manufacturer
-
For applications between 6 GHz and 8 GHz, refer to the “REFERENCE DATA” in the datasheet
