SITU3040/3140 .05-40 GHz ExternallyModulated Unamplified Transmitter DATASHEET | JULY 2014 MICROWAVE The EMCORE SITU3040/3140 (Small Integrated Transmitter Unit) is a high-performance externally-modulated transmitter for applications from 50 MHz to 40 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.
