MN725-2500.0000 Product Data Sheet Revision 100909 Voltage Controlled SAW Oscillator MN725-2500.0000 The MN725-2500.0000 Voltage Controlled SAW Oscillator (VCSO) is a member of Spectrum Microwave 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 that is frequency multiplied by 4 to provide output frequencies in the 1500 MHz to 3000 MHz range.
