DATA SHEET – JULY 2009 Small Integrated Transmitter Unit SITU2400 0.05 – 3 GHz, 1550nm Directly Modulated Self-Contained Transmitter The Emcore Small Integrated Transmitter Unit (SITU2400) is a highperformance, directly modulated transmitter for applications with guaranteed performance over the 50 MHz to 3 GHz frequency band. The SITU2400 is a fully integrated unit that contains both the optics and the control electronics. Only DC input voltages and the RF input signal are required for operation. Applications Cellular and PCS AntennaRemoting Microwave Delay Lines Frequency Distribution Systems Radar System Calibration Phased Array Antenna Systems Features Integrated high-powered 1550 nm DFB laser and bias control circuitry - Only DC input voltages and RF input required High Dynamic Range 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. The unit operates at a nominal optical wavelength of 1550 nm and ITU wavelengths are available for CWDM and DWDM applications.
