滤波电路(毫米波雷达)

Filter Circuits (Millimeter wave radar)

• Set circuit movements are stable due to stable temperature characteristics.

[Temperature Characteristic Data]

• Set power efficiency is improved due to the film capacitor's low loss.

• Film capacitor has excellent high frequency characteristics.

[Frequency Characteristics Data]

[Shock Noise Measurement Data]


Film capacitors do not generate shock noise because they do not experience piezoelectric effect.		When mechanical shocks, such as a light tapping on the board occur, Ceramic X7R generates shock noise.(piezoelectric effect)

• Ceramic X7R experiences reduced capacitance due to applied bias voltage.

→Film capacitor does not experience a reduction of capacitance.

[Dielectric Absorption Data]

• Millimeter Wave Radar
