At The Radar Level gauge Antenna emits and Narrows at The Microwave Pulse. This Pulse propagates in Space AT at The Speed of Light. The When IT Encounters at The Surface of at The the Measured Medium, Part of the ITS Energy IS the REFLECTED the Back and Received by at The Same, Antenna. At The Time interval The Between the transmitted pulse and the received pulse is proportional to the distance from the antenna to the surface of the measured medium.Because the electromagnetic wave propagation speed is extremely high, the time interval between the transmitted pulse and the received pulse is very small (on the order of nanoseconds). It is difficult to confirm. The 90X series 26G radar level gauge uses a special demodulation technology To accurately identify the transmitted pulse and the time interval of the pulse is received to further calculate the distance of the antenna from the surface of the measured medium.

40Gb/s DQPSK Receiver
The integrated DQPSK receiver incorporates an optical phase demodulator (delay-line interferometer or DLI) with 2 pairs of balanced photo-diodes and 2 linear TIAs into a single butterfly package. Compared with the currently available discrete solution in which a separate DLI and a separate receiver are used, the integrated DQPSK receiver eliminates labor intensive fiber routing and coupling (between the DLI and the balanced receiver) as well as the skew control. Moreover, the integrated DQPSK receiver offers a smaller footprint suitable for today’s demanding high speed transponder applications.

DPSK Demodulator
Optical differential-phase shift keying (DPSK) provides a desired modulation format that offers high receiver sensitivity, high tolerance to major nonlinear effects in high-speed transmissions, and high tolerance to coherent crosstalk. In DPSK, data information is carried by the optical phase difference between adjacent bits. For direct detection of DPSK signal (by conventional intensity detectors), a DPSK demodulator is needed to convert the phase-coded signal into an intensity-coded signal.
