One of the great things about the Arduino environment is that it covers a wide variety of hardware with a common interface. Importantly, this isn’t just about language, but also about abstrac… ...

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 ...

While the load is >200 ohm below 5 MHz, in that 10 MHz to 20 MHz region it is actually a pretty heavy load to the FDA for distortion purposes. ... Passive filter options achieve very high SNR, SFDR in ...
