MN725-0400.0000 Product Data Sheet Revision 022210 MN725-0400.0000 Voltage Controlled SAW Oscillator DESCRIPTION The MN725-0400.0000 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.
