SITU3000

The SITU3000 is a high performance externally modulated transmitter for applications from 50 MHz to 18 GHz. The SITU 3000 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.

Features of the SITU3000 are:(1)50 MHz--18 GHz; (2)high dynamic range; (3)fully integrated unit; (4)bias control circuits for laser and modulator.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.

The absolute maximum ratings of the SITU3000 can be summarized as:(1)storage temperature range:-40 to 70;(2)optical output power:7dbm;(3)wavelength:1550dbm;(4)RF input power dBm:0 to 25dbm;(5)frequency range:5 to 18GHz.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.The products described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
