Q Microwave offers Custom Filters and Standard Filter Product Series. Special product lines that address specific industry requirements are available for review under our Key Product Lines. Typical delivery time for prototype filters range from 2 to 6 weeks with up to same-day service available in urgent situations.

 

STANDARD FILTER PRODUCTS

Q Microwave´s catalog parts are initially categorized by topology (lumped element, combline, or ceramic resonator) and then again by filter function (bandpass, lowpass, or highpass). Q Microwave has developed a Design Tool to assist our customer in developing an appropriate specification for their specific filter requirement. With a desired filter specification, you can either forward your requirements to our sales team or follow the below Q-Series links to determine standard part numbers and specifications.
