Programmable Delay Line Based High-speed PPM Modulator with 40 ps Time Resolution

TR-PPM optical test

TR-PPM optical tests have been conducted. Recently a successful TR-PPM optical transmission was made. This is a great achievement and another step closer to developing energy efficient data transmission schemes without a big data transmission speed compromise. As it can be seen from the picture above, at around 20 kilo-meters of optical cable was used

Programmable Delay Line Based High-speed PPM Modulator
with 50 ps Time Resolution

In the past few months we have successfully developed a High-speed pulse position modulator. Modulator uses programmable delay microchips which can be programmed by controlled by FPGA. Altogether the modulator board can generate transmitted reference signals with up to 256 positions and with a time resolution as low as 50 ps. For further information please

Participation Swedish Microwave Days 2023

Our team took part in The Swedish Microwave Days 2023 (SMWD 2023) conference. On may the 25th we presented research about the pulse expansion by the use of Microstrip low pass filters. The presentation (see below) “Microstrip Low-Pass Filter Based Picosecond Pulse Expansion for PPM demodulation” focuses on the topic of expanding the pulses used
