Radio Design 101 - Finishing the Receiver (Episode 6)

In this episode of Radio Design 101 we finish the receiver design by creating an IF amplifier and demodulator, and then assemble and demonstrate the final product. A limiting IF amplifier is used to address the 100 dB dynamic range of signals typical at a receiver's antenna input. The demod is a classic quadrature architecture that uses a mixer and phase shifter, and leverages what we learned in Episode 5. Details of design, construction, and testing are presented, together with comments on how the overall Radio Design 101 course material is applicable to virtually all radio design work, including modern RF integrated circuits.
