The Z Power style resistor gives a better frequency response with similar thermal properties in the same size package. The below chart illustrates the advantage to both RF performance and power handling associated with various Z Power conﬁguration products. Using this technology, designers have novel and exciting combinations available by selecting the ideal thickness, package, aspect ratio and terminal geometry. When looking for a high power, high frequency resistor without compromise, the N-Series Z Power resistor is recommended. These designs have already been successfully deployed in today’s hi-tech applications.

To take the power handling one step further, IMS has implemented a “scrub-cut” rather than a traditional L-cut during the laser trimming process. You can see by the color mapping that there is much higher current density in the L-cut resulting in a hot spot while there is almost no current crowding in the scrub cut image.
Utilizing a smaller input terminal improves the VSWR at elevated frequencies. Compared to the standard SG the Z Power “SZG” resistor has a drafted resistor body to minimize input termination width diﬀerences from the trace. The Z Power resistors use a “scrub-cut” or edge-trim for tuning within a 2% tolerance. The combination of these 2 manufacturing characteristics maximizes the frequency performance.
By changing the aspect ratio on the resistor the “term to term” distance is shortened giving the component a better frequency response at higher frequencies.
NDR-2010SZG has a 1.2:1 VSWR (RL of -20dB) at 4.25GHz while the NDR-1020SZG has a 1.2:1 VSWR (RL of -19.8dB) at 5.45GHz with similar power ratings of 100W – 200W depending on the level of thermal management involved.
