I would like to use the HMC431 in an application at 5.8GHz.but for simulated; I have not found the S-parameters on Hittite website.
Can you please help me to find the S-parameter data for HMC431? Thanks.
We only have output return loss data for theHMC431LP4E which I've attached. At 5.8GHz the return loss is 8.5dB which results in a one-way transmission loss is of only 0.66 dB so there's not much to be gained as far as matching. With all due respect, there's a buffer amp after the VCO so without the full VCO & buffer amp design simulating to improve the match is a waste of time. If you really need more output power I'd look at adding one of our 50Ω gain blocks or using the HMC358MS8G.
Thanks for your reply.
to use the HMC358MS8G with buffer amp , can you give me information about return loss data S11 ?.
because I work on the Ansoft EM software and it need S-parameter data.
