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.
