Q Microwave offers custom filters and standard filter product series. 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). 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.

• Lumped Element Filters - Q Microwave´s miniature lumped-element filter capability extends the full frequency range of our capability: 20 MHz to 20 GHz. The principal advantage of this type of filter is its small size. Disadvantages include higher loss for a given rejection requirement. Typical prototype delivery is 2 to 4 weeks.
• QLB Series Bandpass Filters
• QLL Series Lowpass Filters
• QLH Series Highpass Filters
  
• QLN Series Notch Filters

 

 

• Combline Filters - Q Microwave´s standard combline filters are available from   1  to 40 GHz. The primary advantage of combline filters is the low loss and high rejection  capabilities. Disadvantages include large size and weight compared to lumped element filters. Typical prototype delivery is 4 to 6 weeks.
• QCB Series Bandpass Filters
• QCN Series Notch Filters

 

 

 

• Ceramic Resonator Filters - Q Microwave´s ceramic resonator filters offer  the middle ground in  performance between lumped-element filters and combline filters over the range of 500 MHz to 6 GHz. The standard product is provided in an SMT package. Typical prototype delivery is 4 to 6 weeks.
• QRB Series Bandpass Filters
• QRN Series Notch Filters
