Description
The DB-2933-54 is a RF broadband power
amplifier intended for linear or nonlinear operation
over the band 1.6 to 54 MHz using 2x SD2933
gold metallized N-channel MOS field-effect
transistors. The temperature compensating
biasing circuit supports class B and class AB
operation.
DB-2933-54 is designed in cooperation with
Specific RF Devices.
