IPP’s line of feedback resistors are designed to support wideband RF/Microwave solid-state transistor power amplifiers, which require positive feedback. Using negative resistive feedback is a simple way to improve transistor amplifier stability and frequency gain sloping. These feedback resistors are flange mounted and designed to fit directly over the transistor using the same mounting holes as the transistor. This mounting configuration utilizes normally unused space above the transistor without taking up valuable PCB area adjacent to the transistor. In addition to saving space, this mounting arrangement decreases parasitic inductance associated with resistor leads by providing the shortest lead length possible between the transistor input and output.
