Description
Spectrum Microwave’s Series MDR6100 Phase
Locked Oscillators use a Dielectric Resonator in
the resonant circuit. The circuit is lightly loaded to
obtain the lowest phase noise possible.
The resonator is epoxied 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.
Notes:
1. Specifications labeled “min.” or “max.” are guaranteed in a 50 Ohm system over the
specified temperature range.
2. Output frequency must be specified, and it is an integer multiple of the internal crystal
reference frequency.
3. Mechanical tuning of PLO in unlocked mode.
4. Higher output power is available.
5. Phase Noise at offsets <100 kHz is dependent on external reference and can be
approximated as follows: Phase Noise (dB) = 20log(N) +3 dB above the external reference
phase noise, where N = multiple of reference.
6. Other input voltages are available.
7. Actual or impending loss of lock.
8. Package must be verified by Spectrum Microwave.
