Could you provide me HMC457 nonlinear model for AWR/ADS or S-parameter? I design a HMC457 board, but don't find these files to simulate.
Unfortunately, we do not have large signal models for HMC457. Spars and the datasheet plots can be used for simple calculations.
Non-linear Keysight Genesys models for about 100 ADI RF amplifiers are on the web, but HMC457 is not one of them.
Similarly, ADISimRF software also has 100 RF amplifier models, but not HMC457.
