10 GHz Signal Source
YIG Series
-
The SC5503B and SC5502A are designed to meet demanding low phase noise applications. This is accomplished by employing a multiple phase-locked loop architecture as well as a YIG oscillator as the heart of its synthesizer. Frequency accuracy is provided by an onboard 10 MHz temperature compensated crystal oscillator (TCXO) which can be phase locked to an external reference source if required. These modules can be used as standalone CW signal sources or as LO sources for frequency conversion systems such as the SignalCore IQ modulators and demodulators. They are designed to meet the requirements of many modern applications such as wireless device testing, software-defined radio research, point-to-point radio, multi-channel coherent systems, and other academic and military programs.

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.
