Description
Spectrum Microwave’s Series 600 Phase Locked
Oscillators use a High “Q” Dielectric Resonator in
the resonant circuit. The circuit is lightly loaded to
obtain the lowest phase noise possible.
The resonator is screwed to a printed circuit
board and well grounded to minimize modulation
sidebands during shock and vibration.
Isolators 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.
