DATASHEET | JULY 2014
MICROWAVE
The EMCORE SITU3018/3118 (Small Integrated Transmitter Unit) is a high-performance externally-modulated transmitter for applications from 10 MHz to
18 GHz. The SITU family 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.
The broad bandwidth of the unit makes it ideal to construct transparent links
for microwave antenna signal distribution, Electronic Warfare (EW) systems and
Applications
„„ Microwave Antenna Signal Distribution
„„ Broadband Delay Line and Signal Processing Systems
satcom systems. Other applications include delay lines, signal processing, radar
system calibration, phased array antennas and other systems where it is necessary
to transport RF and microwave signals over long distances without signal degradation.
The system operates at a nominal optical wavelength of 1550 nm. Wavelength
selected lasers on the ITU grid are also available for WDM applications.

Absolute Maximum Ratings
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.
