The Emcore Small Integrated Transmitter Unit (SITU) is a high
performance externally modulated transmitter for applications from 50
MHz to 18 GHz. The SITU3000 is a fully integrated unit that contains
both the optics and the control electronics. Only DC input voltages and
the RF signal are required for operation.
Applications
Microwave antenna signal
distribution
Broadband delay-line and
signal processing systems
Frequency distribution
systems
Radar system calibration
Phased array antenna
systems, interferometric
antenna arrays
The units can be used to construct transparent links for antenna
remoting. The broad bandwidth is intended for applications such as
electronic warfare and Ku band systems. Other applications include
delay lines and signal processing systems.
The system operates at a nominal wavelength of 1550 nm. Wavelength
selected lasers on the ITU grid are also available for WDM applications.

Absolute Maximum Ratings
DATA SHEET – MAY 2008
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute
stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those
given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can
adversely affect device reliability.
