High-Performance RF Filters

Smartcom is a trusted RF filter manufacturer in Bangalore. Offering a complete portfolio from DC to 18 GHz with low insertion loss and high rejection.

What is an RF Filter?

An RF filter is a passive RF component that passes desired frequency ranges while attenuating unwanted signals. RF filters play a critical role in reducing interference, improving receiver sensitivity, and protecting RF front-end components.

Smartcom offers:

RF Low Pass Filters
RF High Pass Filters
RF Band Pass Filters
Custom RF Filter Design

RF Low Pass Filters

RF low pass filters allow frequencies below a defined cutoff frequency to pass while suppressing higher-frequency harmonics and spurious signals. These filters are commonly used in transmitter output stages and harmonic suppression applications

RF Band Pass Filters

RF band pass filters allow only a specific frequency band to pass while rejecting signals outside the band. These are essential in receivers, transmitters, and frequency-selective RF subsystems.
