In the last edition of Don’t Fear the Filter, we built up two examples of the simplest and most-used active filter of all time: the two-pole Sallen-Key lowpass. This time, we’re going to put two of ...

Bandpass filters are indispensable in modern communication, radar, and imaging systems, serving to isolate desired frequency ranges while attenuating unwanted spectral components. Contemporary ...

An electronic circuit that accepts a signal and filters out unwanted frequencies, allowing only a particular frequency or frequency range (band of frequencies) to reach the output side. See bandstop ...

Switched-capacitor filters that are preset for a given bandwidth sometimes do not deliver the bandwidth or Q an application requires. By inverting the clock between two switched-capacitor bandpass ...

Bandpass Filters are used to selectively transmit a portion of the spectrum while rejecting all other wavelengths. Yutai Optics offers a wide variety of Bandpass Filters in a range of bandwidth ...

With the narrowest bandwidths and highest transmission in the industry, Alluxa’s thin-film, ultra-narrow bandpass filters will optimize the performance of laser based systems. Ultra-narrow filters are ...

The UF1500B is rated for 1.5 kW average power, and the UF5000B can handle up to 5.0 kW When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. CHANDLER, ...

The BPC10087 bandpass filter offers less than 0.5-dB insertion loss at a 10-GHz center frequency, and less than 0.7-dB ripple over the 9.6- to10.4-GHz passband. The part also delivers a typical ...

One of the great things about the Hackaday community is how quickly you find out what you don’t know. That’s not a bad thing, of course; after all, everyone is here to get smarter, right? So let’s ...
