Murata High Frequency Ceramic Capacitors, GQM, GJM Series

Chip structure for Murata GQM Series
The Murata GQM and GJM Series High Frequency Ceramic Capacitors are typically used in applications with high frequencies from 500MHz to 10GHz. Featuring improved low power consumption for mobile telecommunications, the GQM and GJM Series have copper electrodes that allow for ultra low ESR, high Q in the GHz frequencies. The GQM series includes the world's first 500 Volt, High Q MLCC capacitor with base metal electrodes ( GQM22 series).

GQM Series - 0603, 0805, 1111

The Murata GQM Series High Frequency Ceramic Capacitors are typically used in applications with high frequencies from 500MHz to 10GHz, such as base stations for cellular, broadcast satellites, cable TV and telecommunication networks, PGS, Bluetooth®,and TV set-top boxes. Featuring improved low power consumption for mobile telecommunications, the GQM Series has copper electrodes that allow for ultra low ESR, high Q in the GHz frequencies and high RF current handling capability. The Murata GQM Series High Frequency Ceramic Capacitors is the best choice for high performance, high power RF designs requiring voltages up to 500VDC. Offered in EIA sizes 0603, 0805 and the new 1111 size with a capacitance range of 0.1 to 100pF, there are a variety of tight tolerance versions available.

GQM22 Series
The Murata GQM Series includes the advanced GQM22 Series - the world's first 500 Volt, High Q MLCC with base metal electrodes. Ideal for high frequency applications such as power amplifiers for base stations, the advanced capacitor also provides low equivalent series resistance (ESR). Developed using Murata 's new base metals technology and superior co-fired ceramic materials, the GQM22 series eliminates problems normally associated with base metal electrodes while providing improved features. The new capacitor does not require characteristic adjustments, an issue common with other base metal electrode high voltage capacitors , yet it offers a 40 percent improvement in Q at 1Mhz compared to general-purpose medium and high voltage capacitors. In addition, the GQM22 series(2.8mm x 2.8mm x 1.15mm) affords capacitance ranging from 0.5pF to100pF and can be used for tight tolerance products around a capacitance tolerance of B(±0.1pF) and C (±0.25pF). These features are best for matching or coupling circuits used in applications such as power amplifiers for mobile communication, WiMAX and LTE base stations, as well as other related high frequency RF modules, and will help improve the high frequency characteristics of the equipment.
