ADS_Phased array_coupled oscillators - RF Cafe Forums

RF Cafe Forums closed its virtual doors in late 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2012, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts. Here is the full original RF Cafe Forums on Archive.org

Good afternoon,

I am studying electrical engineering n' computer science.I use ADS2002(Advanced Design System ) of Agilent for my final project. My diploma thesis is about linear phased array based on coupled oscillators. I am using 4 VCOs(fixed frequency oscillators by varactor) and I couple the consecutive VCOs with a coupling network, which have 2 resistors and 1 transmission line.I have many problems to simulate this circuit in ADS2002, because I do not know how I should simulate 4 VCOs which belong to the same schematic(For example,I can not understand about where the oscport should be placed, which must be only one in the whole circuit). I would like to take some figures about the transient, locking and steady state of the system and its phase dynamics. Could you help me with some advices or tutorials or anything else which will be useful for me? I really need help..

Thank you in advance, Panos
