Features
High Frequency High Q Type 1608(in mm)/0603(in inch) Size Min.
GQM Series
High Frequency Capacitor Ideal for PA Design of Base Stations
Mainly ideal for base stations of mobile communication devices and temperature compensation
of related modules.
1
High Q and low ESR in VHF, UHF and microwave frequency bands.
2
This product is ideal for temperature compensation of high frequency circuits, such as resonant circuits,
tuning circuits, and impedance matching circuits where the operating characteristics of the device are greatly
affected by the capacitance fluctuation.
High Q and low ESR were achieved at a high frequency by adopting ceramic material as the dielectric material
which enables an extremely low loss at high frequency, and base metal electrodes as the internal electrodes.
