400 MHz to 2700 MHz 0.5 W high linearity silicon amplifier
7. Thermal characteristics
[1] Defined as thermal resistance from junction to GND pad.
8. Static characteristics
[1] The supply current is adjustable. See Section 8.1 “Supply current adjustment” and Section 12 “Application
information”.
[2] See Section 12 “
Application information”.
8.1 Supply current adjustment
The supply current can be adjusted by changing the value of external ICQ resistor (R2).
