TMOD Compact Fixed Frequency
Description
The TMOD is a compact low heat dissipation fixed frequency driver for AO modulators and frequencyshifters. The TMODxx drivers are based on oscillators and provide fixed frequencies such as 40 MHz, 80MHz, 110 MHz… This driver has got an integrated amplifier which delivers the necessary RF power to drivethe associated acousto optic device. The RF power can be externally modulated with convenient input signals analog + digital. Cooling is assured by conduction through baseplate for the OEM version.
Key Features:
Fixed frequency in 20-160MHz
Compact size
Low heat dissipation
Dual AM controls analog+digital
High extinction ratio
Output power up to 2.5W
RoHS compliant
