Is using HMC659-Die with Vdd=5V Idd=100mA possible (recommended)?
We have not tested HMC659 with Vdd=5V. Decreasing Vdd will typically increase gain, after some point this can extra gain can cause instabilities. We suggest to test yourself and use HMC659 if the results are stable and meet your requirements. Other than that we do not foresee any failure issues with Vdd=5V.
