Spectrum Microwave, Inc. www.SpectrumMicrowave.com 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. 2707 Black Lake Place Phila, Pa. 19154 PH: 215-464-4000 FAX: 215-464-4001 Rev. 3/19/09 PHASE LOCKED OSCILLATOR MODEL MDR6100-15000 (15 GHz) Outline Drawing Spectrum Microwave, Inc. www.SpectrumMicrowave.com 2707 Black Lake Place Phila, Pa. 19154 PH: 215-464-4000 FAX: 215-464-4001
