The streamlined packaging and interconnect technology offered by Q Microwave make these devices the ultimate choice for filter integration requirements. Additional details on packaging options are available by this link.
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
Hi-Rel Filters
Q Microwave offers space-level filters with quality requirements and documentation tailored to program requirements.
