Wideband Darlington gain blocks have become a workhorse for RF wireless and wireline applications. The broadband linearity and direct-coupled performance has found a multitude of commercial design-ins for base station pre-drivers, repeater-pole transceivers, fiber optic transceivers, CATV and instrumentation systems. One of the drawbacks of existing Darlington amplifier solutions,...

Splitting an RF input signal within a VCR or television was never much of a design challenge for manufacturers when the signal was analog. That changed dramatically, however, when CATV systems made the transition from analog to digital to provide addressability, video on demand, Internet access and other services....
