MN725-0625.0000
Voltage Controlled SAW Oscillator
DESCRIPTION
The MN725-0625.0000 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.
