exactly how difficult is it to produce a synthesizer to produce frequencies between 35 MHz to 4.4 GHz? [OpenTechLab] discovered a rash of boards based on the ADF4351 that might do just that priced at under $30. He chose to get one as well as try it out as well as you can discover his video results below.
At that cost point, he didn’t expect much from it, however he did want to try out it to see if he might utilize it as an low-cost piece of test gear. The video is rather extensive (and evaluates in at almost an hour as well as a half). It covers not just the gadget from a software application as well as output point of view however likewise talks about the theory behind these devices. [OpenTechLab] even sniffed the USB connection to discover the protocol utilized to speak with the device. He wasn’t excessively amazed with the performance of the board however was pleased sufficient with the results at the cost as well as he plans to make some jobs with it.
We’ve seen a great deal of lower-frequency synthesizers utilized for whatever from transmitters to antenna analyzers. While they are handy, it is essential to recognize that dealing with RF typically needs much more than just wiring up a chip as well as linking it to an antenna.
