5021TR Series DFB Transceivers

The 5021TR Series DFB transceivers deliver unmatched performance for radar testing, signal processing, phased antenna array, and phase noise testing. This rugged device eliminates many of the problems that are inherent in alternative transceiver technologies. When used in conjunction with the 355A fiber optic delay spools they offers performance that is superior to acoustic wave and coaxial delay lines.

EMCORE’s fiber-optic transceivers 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 transceiver provide 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. The small size of these components allows for a long delay in a compact package with superior temperature stability of fiber.
