Frequency Mixer,Microwave Radio Frequency Double Balanced RF Mixer Suitable for Connecting Most Devices

you can take an entire course including topics in this video through our website and get a certificate of completion from rasov the online educational radio frequency institute located in Irwin California instructions and coupon for taking this course is provided at the end of this video in this section and we are going to discuss about mixer which is one of the most important blocks that's used inside transmitter and receiver so what is mixer it's a 3 port passive or active device that can modulate or to modulate signal and also we can say it's used for up conversion and down conversion we are going to talk about this in coming slides the purpose is to change the frequency of electromagnetic signal while preserving every other characteristics such as phase and amplitude so actually we try to do that but we know that it's the phase and especially the amplitude is not constant in mixing
