We are using the HMC921LP4E 2 watt amplifier at 400 MHz as a power amplifier for a radio. The PDF datasheet (https://www.hittite.com/content/documents/data_sheet/hmc921lp4.pdf) has a reference design at 450 MHz, but not at 400 MHz. The datasheet says to contact the HMC Applications Group for assistance in optimizing performance for our application. Is this forum the correct place to request a 400 MHz matching design or s-parameters?
Thank you very much,
