Frequency generation is usually a very critical part in every RF design. The higher the target frequency, the higher complexity. Usually. With the ADF4351, Analog Devices offers an effort-saving component level solution for frequencies up to 4.4 GHz. The ADF4351 from Analog Devices (ADI) is a modern wideband PLL synthesizer with integrated low phase noise […]

Review: Abracon ABFT Frequency Translators
In March, 2012, Abracon announced the production of ultra-low jitter, VCXO based frequency translators / jitter attenuators. This is supposed to resolve some problems that accompany classic PLL-based designs at an affordable price. Now, the ABFT frequency translators / jitter attenuators are available on the market and it’s time to have a closer look. The […]

ICS501 – Integrated PLL Clock Multiplier
Before clock multiplier circuits existed, they had to be implemented with discrete parts. This took up quite a bit time in design and prototyping. Luckily the days are over and we can use integrated clock multipliers such as the LOCO™ PLL clock multiplier ICS501. I stumbled across a box of ICS501 PLL clock multipliers from […]

C-Band DRO LNB Teardown
A low-noise block downconverter (LNB) is a key element in a satellite receiver system and is responsible for converting the relatively high frequency of the received signal into the more convenient L-Band. But how do they work and what do they look like on the inside? Let’s have a look! From a theoretical standpoint, a […]
