DATA SHEET – FEBRUARY 2011 Small Integrated Transmitter Unit SITU2300 0.01 – 3 GHz, 1550nm Directly Modulated Self-Contained Transmitter With 30 dB Integrated RF Preamplifier Applications The Emcore Small Integrated Transmitter Unit (SITU2300) is a highperformance, directly modulated transmitter for applications with guaranteed performance over the 10 MHz to 3 GHz frequency band. The SITU2300 is a fully integrated unit that contains both the optics and the control electronics. Only a single DC input voltage and the RF input signal are required for operation. An input RF amplifier increases link performance. Microwave Delay Lines The unit can be used to construct transparent optical links for antenna remoting, microwave delay lines and other applications where it is necessary to transport RF over long distances without signal degradation. Frequency Distribution Systems The unit operates at a nominal optical wavelength of 1550 nm and ITU wavelengths are available for CWDM and DWDM applications.
