A magnetic flux stabilization scheme involving a low-frequency flux-locked loop has been developed to regulate the gain of a radio-frequency amplifier based on a superconducting quantum inteference device (SQUID). The flux-locked loop largely eliminates drifts in the gain arising from drifts in the flux bias. Tests on a microstrip SQUID amplifier operating at 777 MHz inside a superconducting shield show that the peak-to-peak drift in the gain is no more than 0.3 dB/day. © 2001 American Institute of Physics.
