5021T Series DFB Transmitters

The 5021T Series DFB Transmitters deliver unmatched performance for radar testing, signal processing, phased antenna array, and phase noise testing. These rugged device eliminates many of the problems that are inherent in alternative transceiver technologies. When used in conjunction with an EMCORE fiber optic receiver it offers superior performance.

EMCORE’s fiber optic transmitters provide bandwidth that is essentially independent of fiber length, loss or delay, and triple transit signals that are immeasurable. In addition to enhanced electrical performance, the transmitter provides several mechanical advantages. EMCORE’s technology takes advantage of the rigid yet flexible properties of fiber optic cable to provide repeatable enhanced phase and group delay characteristics.
