... I D =1.2A. So the maximum DC - power can be calculated to: This value is smaller than 5W and CW - operation is possible. By decoupling RF power out of the CGY181 the power dissipation of the device can be further reduced. Assuming a power added efficiency PAE the total power dissipation P tot can be calculated using the following formula: ...
