Description
Spectrum Microwave’s Series 600 Phase Locked
Oscillators use a High “Q” Coaxial Resonator in
the resonant circuit. 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.
