Working Principle

A mixer is a nonlinear device that converts an input signal from one frequency to another, usually of a lower frequency. This is accomplished by mixing two signals together and summing the results to create a complex signal. The F1701NBGI is a Gilbert cell mixer, which is a type of mixer that uses two transistors with equal gain to mix two signals. The input signals are multiplied and applied to the input base of both transistors and a voltage is generated at the output. The Gilbert cell mixer is known for its low noise figure and high linearity, making it an ideal choice for a variety of applications.

The F1701NBGI is designed to be used in a variety of applications, providing superior performance with excellent linearity.
