Darlington Gain Blocks Eliminate Bias Resistor
Wideband Darlington RF gain blocks are commonly used in wireless and wire-line applications. Their strong broadband linearity makes them suitable for base-station predrivers, repeater-pole transceivers, fiber-optic transceivers, cable-television (CATV), and instrumentation systems. Unfortunately, conventional Darlington gain blocks need an external-dropping resistor to set and stabilize the bias current. To ensure good temperature stability, an overhead voltage of about 2 to 3 V is applied....
