RM 35MHz High Power Low Pass Filter


Experience superior performance and unparalleled precision with the RM 35MHz High Power Low Pass Filter. Crafted exclusively for radio amateurs seeking professional-grade equipment, this filter effortlessly combines efficiency with innovation.


The RM 35MHz High Power Low Pass Filter is an exceptional addition to your radio amateur equipment collection. Crafted with utmost precision and ingenuity, this product boasts a remarkable 50 Ohm input and output impedance, ensuring seamless connectivity.

Engineered with a cutting-edge 9-pole Chebyshev design, this filter exhibits unparalleled performance in eliminating unwanted signals outside its intended frequency range. With an astonishingly low insertion loss of less than 0.1dB, you can trust that your signal transmission remains uncompromised.

Our experts have further fine-tuned this filter to provide an exceptionally low input VSWR ratio of less than 1.15:1 a testament to our commitment towards excellence. This feature not only guarantees minimal power reflection but also ensures optimal performance across the bands it caters to 12 m, 11 m, and 10 m. At the core of this revolutionary device is its impressive cut-off frequency of 36MHz an ideal characteristic for isolating undesired frequencies while delivering unmatched clarity within the designated bands.

Complementing its outstanding specifications is the ability to handle maximum power without flinching 600W constant carrier or up to a formidable 1200W SSB with unwavering stability.

To enhance durability and maximize conductivity, we’ve incorporated top-grade SO239 Input and Output connectors featuring Teflon insulators and gold-plated terminals into this meticulously designed device. This supreme attention to detail will undoubtedly ensure long-lasting functionality in any challenging operating environment.
