Biphase modulator
WebA double-balanced microwave biphase modulator circuit is provided with a first balun for transforming the unbalanced RF Input impedance to a balanced diode impedance and providing direct current ground return paths, and a second balun for transforming the balanced diode impedance to the unbalanced RF Output impedance and providing … WebOct 24, 2024 · In this letter, we present a low-power vector-sum phase shifter for upcoming 5G communication at 28 GHz. The ±I/±Q signals for phase synthesis by vector adder (VA) are generated by a 90° coupler and two reflection-type biphase modulators. Modulators are only biased at 0 and 1.8 V to avoid large insertion loss near their phase reversal region. …
