Abstract
The double‐junction SQUID is viewed as a parametric amplifier and mechanisms, which place an upper limit on the pump frequency (and thus gain), are investigated. Self‐induced steps in the I‐V characteristics as well as damping of the Josephson oscillation are shown to be two limiting mechanisms.Keywords
