SHF 78121 A Clock Distribution

Published: May. 12, 2016

In setups with digital high speed modules and instruments, the clock distribution is always challenging as some parts require a full-clock, others a half-clock, and some even a lower fraction clock signal. Our latest release, the SHF 78121 A is designed to facilitate such a complex test set ups requiring a range of clock signals.

SHF D836 A Differential to Single-Ended Linear RF Amplifier

Published: Mar. 17, 2016

Differential signals from a high performance DAC, typically needed to be differentially-loaded in order to preserve the linearity and resolution from the impact of commom-mode spurious.  In addition, state-of-the-art DP-QPSK modulators for 16QAM applications are driven single-ended and require linear drive voltage of up to 4 V.  The newly released SHF D836 A differential input, single-ended output linear driver amplifier makes a perfect interface between a high performance DAC and a PM QPSK modulator for 16QAM.

SHF 46121 A Optical Transmitter

Published: Feb. 29, 2016

Our family of compact low cost instruments has been extended to include the SHF 46121 A C-band only optical transmitter. Compared to the earlier release SHF 46120 A, the new module supports higher speeds up to 50 Gbps in ASK and 32 GBaud PAM4 mode. This is realised by utilizing a different modulator which only works in C-band.
