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. 2707 Black Lake Place Phila, Pa. 19154 PH: 215-464-4000 FAX: 215-464-4001 Rev. 9/22/08 PHASE LOCKED OSCILLATOR MODEL 611230 (1600 MHz) Outline Drawing Spectrum Microwave, Inc. www.SpectrumMicrowave.com 2707 Black Lake Place Phila, Pa. 19154 PH: 215-464-4000 FAX: 215-464-4001
