Abstract
In this paper, we present a 22-GHz ultra low
phase noise push-push dielectric resonator oscillator (DRO)
using MMICs fabricated by 2- m GaAs HBT process.
This circuit demonstrated a low phase noise of -114 dBc/Hz and -134 dBc/Hz at offset frequency of 100 kHz and 1 MHz,
respectively. The second harmonic output power is above 6
dBm with a fundamental suppression of over 30 dBc. This
DRO exhibits good phase noise performance based on the
figure-of-merit carrier frequency, offset frequency, and dc
power compared with the reported push-push DRO, which
is due to low 1/f noise HBT and reproducible MMIC chips.
In addition, this is the first reported push-push DRO
implemented using MMICs.
