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.
Internal reference models are also available.
A lock indicator circuit is provided to signal an
out-of-lock condition.
