MN745-0640.00-10.00 Preliminary Specifications Revision 060506 MN745-0640.00-10.00 Phase Locked Voltage Controlled SAW Oscillator DESCRIPTION The MN745-0640.00-10.00 Phase Locked Voltage Controlled SAW Oscillator (VCSO) is a member of Spectrum Microwave’s MN745 series of high performance low noise phase locked SAW oscillators designed for the military applications. The design is based upon a fundamental VCSO in the 375 MHz to 750 MHz frequency range. The phase lock loop bandwidth can be optimized for phase noise and vibration sensitivity. The MN745 series of phase locked VCSOs accepts external reference frequencies up to 32 MHz. FEATURES • • • • APPLICATIONS Combines the high fundamental frequency and low noise of a SAW Oscillator with the frequency stability of a user applied reference.
