RF (Radio Frequency) filters are passive electronic filters designed to operate on a signal from medium to extremely high frequencies and limit the noise and interference caused by strong signals outside specified frequency ranges. These filters allow the specified frequencies within the circuit while unnecessary frequencies are rejected. They are ideal for diplexers and duplexers to separate or combine various frequency bands. In addition, they are used in wireless communications, TVs, and radios.
Types of RF Filters:
They are available in various types, categorized by parameters, such as insertion loss, center frequency, bandwidth, attenuation at maximum and minimum frequency, operating temperature ranges, packaging type, and impedance. We provide different filters that meet all the parameters according to specified applications.
Choosing the Right RF Filter:
Choosing the best filters depends on the parameters required. We offer the following filter results in our inventory: Balance, Band Pass Filter, High Pass Filter, Low Pass Filter, and more.
Band Pass Filter:
The bandpass RF filters only allow through signals within specific frequencies. Above and below the cutoff frequency, the signal is attenuated, passing through the usable radio frequency.
High Pass Filter:
High pass filters are the opposite of low pass filters in various ways. These filters are designed to allow higher signals than the cutoff frequency.
Low Pass Filter:
As the name suggests, these filters allow through lower frequencies.
These filters work the opposite of the bandpass filters by rejecting signals within specific RF bands. These are ideal for eliminating unwanted system signals.
Typical Applications of RF Filters:
Bandpass filters are ideal for all kinds of instrumentation, such as:
- Sonar, and
- Medical applications (like ECGs and EEGs).
- They are best for use in optics, like lasers.
- Low pass filters are employed for audio applications.
