Novel Tunable Mixer Using Double Section Hybrid Coupler for Extended ISM Band ApplicationsPublished in Institute of Electrical and Electronics Engineers Inc.
2023
In this paper, a tunable mixer having a tunable range from 868 MHz to 2.4 GHz is proposed. The structure consists of a modified tunable 3 dB double section hybrid coupler along with a tunable 3rd order low pass filter. The tunibility is achieved by varying the reverse biased voltage of the varactor diode. In the proposed circuit, only one control voltage is applied with RF choke inductors. For mixing operation, two schottky diodes are used. Working methodologies of the proposed mixer is established with extensive simulation results. Finally, proposed design gives wide tuning range, high port isolation, good return loss throughout the frequency range over 868 MHz to 2.4 GHz. © 2023 IEEE.
