Model 148
OCXO - Ultra Miniature, Ultra Low Power
Shock Resistant
Features
8MHz to 100MHz frequency range
Industry’s smallest OCXO
Fast warm-up (to 45s)
Eco-friendly < 200mW power consumption
HCMOS output
Shock and vibration resistant construction
RoHS Status
Applications

Instrumentation / Test and Measurement
Description
The Model 148 uses an SC-cut crystal technology with arrangement of the whole oven system together with the
crystal oscillator inside the TO-8 vacuum holder to radically reduce the OCXO size, power consumption, and its
warm-up time. As a result, the Model 148 provides excellent temperature stability, low phase-noise and aging.
Special internal heating resonator (IHR) design enables extra-high shock resistance and durability - a distinctive
feature of this model.
