The circuit is lightly loaded to obtain the lowest phase noise possible. The resonator is soldered to a printed circuit board and well grounded to minimize modulation sidebands during shock and vibration. Buffer amplifiers are used to provide isolation from load VSWRs; Regulators filter noise on the DC input voltage. External reference models are also available. A lock indicator circuit is provided to signal an out-of-lock condition.
