MN725-0500.0000 Product Data Sheet Revision 032510 MN725-0500.0000 Voltage Controlled SAW Oscillator DESCRIPTION The MN725-0500.0000 Voltage Controlled SAW Oscillator (VCSO) is a member of Spectrum Microwave’s MN725 series of high-performance low noise SAW oscillators designed for the military applications. The hermetic kovar package and rugged hybrid construction provide low vibration sensitivity and performance over a wide operating temperature range. The highly repeatable and linear tuning range makes the MN725 family of VCSOs ideal for phase locked applications. The design is based upon a fundamental VCSO in the 375 MHz to 750 MHz frequency range.
