Voltage Controlled SAW Oscillator
MN725-1250.0000
DESCRIPTION
The MN725-1250.0000 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 2 to
provide output frequencies in the 750 MHz to
1500 MHz range.
