Frequency-Changer Modifications TRIZ Cases
- Oversampled LO Harmonic Rejection Mixer for Cleaner Frequency Translation
Using oversampled sine-wave local oscillators, this mixer suppresses LO harmonics that conventional filters miss, improving output signal quality.
- Reconfigurable Heterodyne Mixer for Parasitic Signal Suppression
Remote-controlled phase shifters let a heterodyne mixer suppress intermodulation products across changing RF and oscillator spectra.
