Wideband RF Amplifier

This is a circuit of Wideband RF amplifiers. This circuit use current-feedback components like the THS3202. The THS3202 was chosen because it has fast slew rate and wide bandwidth. The amplifier voltage gain of this circuit is 20 and stage voltage gain of this circuit is 10. Here is the circuit:

Compared to traditional RF circuitry, this circuit is simpler. This circuit just require two resistors, op amp, decoupling components and the termination. the stage gain is set by The 301-O (RF) and 16.5-O (RG). [Source: Texas Instruments Application Note]
