IPP’s line of Feedback Resistors are designed to support wideband RF/Microwave solid-state transistor power amplifiers, which require resistive 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 RF/microwave 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. The short lead length and corresponding lower inductance allow for higher frequency operation.
Our feedback resistors are constructed using nickel-plated aluminum flanges with BeO ceramic resistors, providing excellent thermal conductivity and low parasitic capacitance. These products are available in a range of resistor values and power levels to match various applications. Flange styles are designed with mounting holes to match up with many popular transistor footprints. Feedback resistors are available with or without DC blocking capacitors, and values can be customized as required.
