Introduction

B39311R096H110, manufactured by the German electronics firm Infineon, is a dual-band resonator. It is a second order high quality factor (Q) band pass filter which derives its performance from the use of a piezo-electric ceramic resonator. As such, it is a versatile and reliable device for use in a wide range of applications.

Subwavelength Properties

B39311R096H110 is a subwavelength-sized resonator and is capable of producing an amplified signal in the frequency range of 2.4 GHz - 5.5 GHz. It has a fractional bandwidth of less than 0.5% and exhibits excellent electrical characteristics in terms of high Q-factor and good return loss. The resonator resonates at a frequency in between its two half-wavelengths, enabling a band pass behavior with high-frequency selectivity while maintaining low-noise characteristics. Furthermore, it features a low profile, allowing it to be used in space constrained applications.

Technology

The B39311R096H110 dual-band resonator is built upon an embedded ceramic multi-layer technology which provides superior electrical characteristics and reliable performance in highly dynamic applications. It is constructed using an aluminium nitride-based substrate, with gold layers and polyimide insulation layers. The multi-layer configuration ensures efficient signal transfer from the resonator to the surrounding circuitry, while providing effective interior temperature and mechanical stability.

Application Fields and Working Principle

The B39311R096H110 dual-band resonator has a wide range of applications due to its excellent electrical characteristics. It is commonly used in wireless chipset, Bluetooth and Wi-Fi applications, as a low spectrum microwave band-pass filter for ECU, for WiMAX and for antenna applications.The device works on the principle of resonance. When an alternating current passes through it, the piezo-electric ceramic material in the resonator vibrates, and resonant frequency can be obtained from the type of this material and its physical geometry. This resonant frequency is amplified and filtered to enable a high level of selectivity. With its high Q-factor, the resonator can reject all other frequencies and only the signal at the center frequency is passed through. This allows for efficient signal processing, with maximum signal-to-noise ratio, minimizing unwanted noise.

Conclusion

The B39311R096H110 dual-band resonator provides a high level of performance in a highly versatile form factor. With its excellent electrical characteristics, wide range of applications and reliable performance, this device is ideal for use in a range of applications. Due to its subwavelength properties, the device is able to provide a high quality signal with minimum noise and high Q-factor, making it an ideal choice for modern electronic systems.
