Frequency Performance Comparison

This chart compares the frequency response of the CH series resistors versus standard chip resistors at high frequency up to 70 GHz. The graph shows how well the frequency-dependent impedance of the resistor tracks against its ideal resistance value. The goal is to achieve as close as possible to a one-to-one ratio of impedance to ideal resistance consistently across the entire operating frequency range. CH series resistors maintain a relatively flat impedance up to 70 GHz, while standard thin-film or thick-film resistors of similar size start to deviate significantly from the ideal value between 10 GHz and 20 GHz. Achieving consistent impedance is critical in millimeter-Wave applications, as it helps maintain signal integrity.
