Cavity Filter
The Cavity Filter by Keenlion provides accurate signal selection and high power handling ability. The filter performs between 8000 to 12000 MHz. It only has an insertion loss of 0.5 dB maximum and provides very high signal rejection of a minimum of 70 dB. This filter is excellent in base stations as well as radar systems since it can transmit strong signals without failure.
Band Pass Filter
This Band Pass Filter operates at frequencies between 4 and 8 GHz. It filters out signals you do not require having high selectivity and sharp roll-off. It is very good in wireless communications, as it only loses 1.0 dB and has a VSWR of 2.0:1 or less. The signal modification is small.
Band Stop Filter. Keenlion Band Stop Filter eliminates unwanted frequency bands by providing a rejection of ≥50 dB. This filter operates between 1530 and 1606 MHz and is suitable to shield sensitive equipment in telecommunications and industrial applications against interference.
Low Pass Filter
The Low Pass Filter of Keenlion retains low-frequency signals and filters out high-frequency signals. It is commonly used in audio and RF systems due to its low insertion loss of 0.5 dB and 3 GHz cutoff frequency to eliminate high-frequency noise.
Microstrip Filter
When board space is at a premium and budget matters, our Microstrip Filter is your ideal partner. Designed for the 1-6 GHz range, this filter is built for seamless integration into modern, dense electronic assemblies. Think of it as the perfect citizen on your PCB: it plays well with others, is easy to manufacture at scale, and delivers reliable performance with a low insertion loss of ≤1.2 dB. It's the cost-effective, high-performance choice for integrated systems where every millimeter counts.
Dielectric Filter
For applications where the environment is as demanding as the performance specifications, turn to our Dielectric Filter. Engineered for the 1.5-3.5 GHz range, this filter excels in advanced communication systems that cannot afford drift or degradation. Its core strength is exceptional frequency stability, ensuring consistent performance where other filters might falter. Coupled with a low insertion loss of ≤1.0 dB, it provides the robust and reliable signal conditioning required for mission-critical infrastructure.
LC Filter
Sometimes, classic technology offers the most elegant solution. Our LC Filter, operating from 100 MHz to 6 GHz, utilizes precisely tuned inductors and capacitors to deliver exacting signal control. With a consistent insertion loss of ≤1.0 dB, it's a versatile and trusted component across countless applications. You'll find it cleaning up signals in sensitive power supply lines or shaping waveforms in complex processing circuits, proving that fundamental design executed with precision remains indispensable.
High Pass Filter
Low frequency interference and noise can obscure vital data. Our High Pass Filter is designed to clean up your signal path by effectively blocking these unwanted lower frequencies while allowing everything above its 5 GHz cutoff to pass freely. With a sharp roll-off and minimal insertion loss (≤1.0 dB), it's commonly deployed in RF systems to isolate bands and in high-fidelity audio applications to ensure crisp, clear output. It's your first line of defense against disruptive noise.
