Small Integrated Receiver Unit
SIRU3040
0.05 - 40GHz
The Emcore Small Integrated Receiver Unit (SIRU3040) is a high-
performance optical receiver with guaranteed performance over the 50
MHz to 40 GHz frequency band. The SIRU3040 is a fully integrated
unit that contains both the high frequency photodiode and the control
electronics. Only DC input voltages and the optical input signal are
required for operation.
Applications
Microwave Antenna Signal
Distribution
Broadband Delay-line and
Signal Processing Systems
Frequency Distribution
Systems
Radar System Calibration
Phased Array Antenna
Systems, Interferometric
Antenna Arrays
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 and microwave signals over long distances
without signal degradation.
The SIRU3040 is an ideal receiver to use with Emcore’s high-
performance externally modulated fiber optic transmitters.
