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.

Internal reference models are also available.

A lock indicator circuit is provided to signal an

out-of-lock condition.
