MtronPTI has introduced a new planar filter line with products that operate over a frequency range from 1.5 to 20 GHz. These planar filters utilize commercial and custom substrates that have a typical insertion loss of less than 1 dB over a very small surface-mount footprint and are typically less than 0.080 inch high. Parameters such as passband, bandwidth, insertion loss, temperature range, size and power handling can be customized based on application requirements.

Key Features of Planar Filter Designs
- Extremely small size and low height
- Low insertion loss (less than 1 dB typical)
- Available from 2 to 50% bandwidth
- Stable over a wide temperature range
Applications of Planar Filters
For over 59 years MtronPTI has been designing and manufacturing various topology filters such as these for industrial, commercial, space, and aerospace and defense customers. As the demand for more robust filter designs increased for frequencies above 2 GHz, MtronPTI’s team developed the ability to design and manufacture planar filters utilizing interdigital, combline, hairpin, edge-coupled and end-coupled topologies.
MtronPTI offers a broad line of precision crystal resonators, oscillators, filters, and Integrated Microwave Assembly solutions for the defense markets. MtronPTI is an ISO 9001:2015 and AS9100 Rev. D certified organization.
