Quarter-Dual-Mode SIW and Microstrip Line Resonator Stabled Feedback Oscillator
In this letter, a low-phase noise feedback oscillator based on a quarter-dual-mode (QDM) substrate-integrated waveguide (SIW) and microstrip line is proposed. By combining a QDM SIW resonator with a microstrip line, a third-order transmission response can be achieved without increasing the occupied area. Two transmission zeros (TZs) are generated at the upper passband to increase the group delay peak and an additional TZ at
$2f_{0}$
to suppress the second harmonic signal. The compact feedback-type oscillator using QDM SIW is designed, fabricated, and measured for the first time, which a circuit size is just about 930 mm2. The experimental results exhibit an output power of 0.22 dBm with a phase noise of −134.66 dBc/Hz at a 1-MHz frequency offset from the oscillation frequency. The oscillation frequency is 10.1 GHz and the corresponding suppression of the second harmonic signal is more than 52 dBc.
