SD2902 Description

Short technical summary and product information.

The SD2902 from STMicroelectronics is a gold metallized N-Channel MOS field-effect RF power transistor. It is engineered for 28V DC large signal applications operating up to 500 MHz.

 

Key electrical specifications include a minimum output power of 15W at 400MHz with a 28V supply voltage and 25mA quiescent current. The power gain is a minimum of 12.5dB, with a typical drain efficiency ranging from 45% to 55%. The transistor exhibits a typical input capacitance of 23pF and output capacitance of 18pF at 1MHz.

 

Absolute maximum ratings specify a drain source voltage of 65V and a drain current of 2.5A. The maximum operating junction temperature is 200°C. Thermal data indicates a junction-to-case thermal resistance of 3.0°C/W.

 

This RF power transistor is supplied in the M113 package, suitable for common source configurations. It is designed for Class A or AB operation and offers excellent thermal stability.
