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.
