PHASE LOCKED OSCILLATOR

MODEL MDR5100-18000 (18 GHz)

Features

Description

! Low Phase Noise: -107 dBc/Hz @ 100 kHz

Spectrum Microwave’s Series MDR5100 Phase

! Low Spurious: -80 dBc Typical

! Internal Reference Design

! Environmental Screening Available

Locked Oscillators use a Dielectric Resonator in

the resonant circuit. The circuit is lightly loaded to

obtain the lowest phase noise possible.

Specifications¹

The resonator is epoxied to a printed circuit

board and well grounded to minimize modulation

sidebands during shock and vibration.

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.
