## Project Description




The primary use of this device is to detect RF power. To power the board, the user will connect a low power DC supply. Then, either an antenna or signal generator will be connected to Port 1 through a sub-miniature version A (SMA) connection.  Once a strong enough signal is created, a root mean square voltage (VRMS) detector will create an output proportional to the input voltage. This voltage will then be processed by an analog-to-digital converter (ADC). A microcontroller will take this as an input and serially connect to a display interface through universal serial bus (USB). The display will provide information such as the VRMS, peak voltage (Vp), and the average voltage (Vavg). In possible future expansions, the board can be upgraded for other vector network analyzer (VNA) measurements such as return loss, insertion loss, complex impedance, resistance, reactance, and standing wave ratio (SWR). Port 2 can be added as well as circuitry such as signal generators, directional couplers, and switches to achieve this functionality. However, many of these new functions will still revolve around the power detector. 

NB: This is a WORK in PROGRESS.
