High Performance RF/microwave Assemblies
We create precision-engineered RF filters and components. Every solution is custom-built to meet demanding specifications for size, weight, power, and durability. Customized bandpass, lowpass, highpass and notch filters, diplexers, and multiplexers, from 1 MHz to 40 GHz.
As RF demands grow, designers are turning to tunable filters and switch filter banks to meet performance goals in both military and wireless systems. Our team applies more than three decades of advanced RF assembly experience to every custom solution.
Smaller. Lighter. More cost-effective.
Lark’s next-generation customizable mmWave filters deliver significant SWaP-C improvements for systems operating between 5 GHz and 40 GHz. Ideal for demanding SATCOM and 5G wireless infrastructure environments.
The mmWave family offers two product lines to choose from mmW-STL and mmW-FH. The mmW-FH filters use a substrate-integrated waveguide design that allows for narrowband designs. These filters are manufactured using PCB processes using low-loss substrates that feature top electrical performance over a wide range of temperatures. Levering PCB processes reduces NRE costs and the time required to prototype, offering the benefits of an off-the-shelf component from a custom filter design that meets your specifications.
The mmW-STL filters are based on a stripline or microstrip design for the smallest footprint for a given frequency. This design supports more traditional bandwidths of 5-20%.
- Small size and lightweight (.25x.25x.033 in or smaller depending on frequency)
- Easily stacked and surface mounted
- Temperature-stable
- Custom yet cost-effective
