The cap in question is part of the guitar’s tone circuit, which along with a potentiometer forms a variable low-pass filter. A rich folklore has developed over the years around these circuits ...

A Butterworth low pass filter processes the DDS signal and then feeds a two-transistor amplifier. The circuit will output about 0dBm into 50 ohms. The power detector is an Analog Devices AD8307 ...

Kyocera AVX has released two new series of compact, thin-film band-pass filters engineered to provide excellent RF performance in a wide range of high-power applications with crowded PCBs.

Figure 4: Pass Band Performance of the Band Pass Filter Summary This paper presents the architecture and measured performance for a new Sampling RF filter technology. This filter is a key RF component ...
