In this article, we will learn about the working of a Superheterodyne AM receiver or superhet for short with the help of a block diagram.

The PLL circuit shown in Figure 1 uses a 13 GHz Fractional-N synthesizer, wideband active loop filter and VCO, and has a phase settling time of less than 5 μs to within 5° for a 200 MHz frequency jump ...

Measuring RF power and return loss in radio or test-and-measurement applications typically involves the use of directional couplers and RF power detectors. This solution combines ...
