EMCORE 357A

35XX Series, 280 μs Max
Fiber Optic Delay Lines
DATASHEET | NOVEMBER 2013
MICROWAVE
The 35XX Series Fiber Optic Delay Lines deliver unmatched performance for radar testing, signal processing, phased array antennas
and phase noise testing. When used in conjunction with either
the 5016A/B/C/D fiber optic transceiver, System 10000 rack-mount
transmitters and receivers, or EMCORE flange-mount transmitters
and receivers, these rugged devices eliminate many of the problems
that are inherent in alternative delay line technologies including acoustic wave
devices and coaxial delay lines.
EMCORE’s fiber optic delay lines provides bandwidth and insertion loss that are
Applications
essentially independent of delay and triple transit signals that are immeasurable.
In addition to enhancing electrical performance, the delay lines provide several
„„ Radar Testing/Calibration
mechanical advantages. EMCORE’s technology takes advantage of the rigid, yet
„„ Signal Processing
group delay characteristics.
„„ Phased Array Antennas
EMCORE’s 35XX Series Fiber Optic Delay Lines consist of three unique
versions:
„„ Phase Noise Processing
flexible properties of fiber optic cable to provide repeatable enhanced phase and
„„ 355A - Flange-Mount
Features
„„ 356A/B - Double-Wide Plug-In, compatible with the System 10000 chassis
„„ Delays Up to 280 microseconds
„„ 357A/B/C/D/E - Rack-Mount, which is integrated into the System 10000 chassis
„„ Various Form Factors
The small size of these components allows for long delays in a compact package
with the superior temperature stability of fiber.
„„ Small Size
„„ Flat RF Amplitude Response and Phase

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress
ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given
in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely
affect device reliability.
