What is a crystal filter?

Crystal filters are electronic filters that use quartz crystals as the resonating elements. They are commonly used in radio frequency (RF) and microwave frequency receiver and transmitter circuits

Crystal filters are available in a number of different selectivity options characterized by the number of resonant elements referred to as the number of poles. For Gollege products this a number between 2 and 8. The greater the number of the poles the sharper the cutoff and the greater the rejection of out-of-band signals but also the larger the package. We are happy to help you chose the right one for your application.

What are crystal filters used for?

The main advantage of crystal filters is their narrow bandwidth, high stability and being passive devices have no power consumption, which makes them ideal for use in narrowband systems where high performance is required without the power penalty of digital processing.

Crystal filters are widely used in some high performance communications applications, such as professional radio, military and aerospace systems, where the performance and stability offered by crystal filters is critical.

Other common applications where crystal filters are used include amateur radio communications and many other types of radio frequency devices. 

What are the advantages of using crystal filters?

Crystal filters offer several advantages, including narrow bandwidth, high stability, and low power consumption. They provide precise frequency control and excellent rejection of out-of-band signals, making them suitable for demanding applications where performance is critical.

How do I choose the right crystal filter for my application?

The selection of the appropriate crystal filter depends on factors such as required bandwidth, selectivity, package size, and performance specifications. Golledge's expert advisers can assist you in choosing the right crystal filter to meet your application requirements.

Can crystal filters be customised to specific frequencies and bandwidths?

Yes, we offer a wide range of crystal filter types and specifications to accommodate diverse frequency and bandwidth requirements. Our products are available in compact packages with competitive pricing, and our expert advisers can assist in customising filters to suit your exact specifications.

Are Golledge crystal filters suitable for high-performance communications applications?

Yes, Golledge crystal filters are widely used in high-performance communications applications such as professional radio, military, and aerospace systems. Our filters offer the stability, precision, and rejection of out-of-band signals required for critical communication systems.

Do crystal filters from Golledge Electronics require any power supply?

No, crystal filters are passive devices and do not require a power supply. They operate solely based on the resonating properties of the quartz crystals, making them energy-efficient and suitable for battery-powered or low-power applications.

What is the typical size of Golledge crystal filter packages?

We offer crystal filters in compact packages to suit various space constraints. The package size may vary depending on the number of poles and performance specifications. 

Our expert advisers can help you select a crystal filter with the appropriate package size for your application.

Can Golledge provide technical support for integrating crystal filters into my system?

Yes, we offer comprehensive technical support for integrating crystal filters into your system. Our team of experts can provide guidance on filter selection, design considerations, and integration best practices to ensure optimal performance and compatibility with your application requirements.

Are Golledge crystal filters compatible with surface mount technology (SMT) assembly?

Yes, our crystal filters are available in surface mount packages for easy integration into SMT assembly processes. Our filters are designed to meet industry-standard footprint and packaging specifications, ensuring compatibility with modern manufacturing techniques.

Can Golledge crystal filters be submerged in liquid environments?

No, Golledge crystal filters are not designed for use in liquid environments. They are electronic components intended for dry, controlled environments. Submerging them in liquid can damage the components and affect their performance. It's important to adhere to the specified operating conditions outlined in the product datasheets to ensure proper functionality and longevity of the filters.

Are Golledge crystal filters suitable for use in high-voltage applications?

No, Golledge crystal filters are not suitable for use in high-voltage applications. These filters are designed for low-voltage signal processing and are not rated for high-voltage environments. Using them in high-voltage applications can result in damage to the filters and pose safety risks. It's essential to ensure that the operating voltage of the crystal filters aligns with the requirements of the application to prevent any potential hazards.
