I'm looking at doing a design with HMC815, but due to the bias requirement of the device, it looks like I would have to use a bias controller.
The controller that looks most suitable for my needs are HMC981, but with this being max 200mA, and the HMC815 wanting 270mA, I would guess this is stretching it too far? Is the HMC980 in any way the same DIE?
If so, as far as I can determine, the only alternative then is HMC920? Given that board space is at a premium (doing soft substrate) and this requires somewhat large external components. This controller is also more expensive than I'd like.
I guess what I'm after is a idea on how to bias this chip, I feel like I'm missing something quite obvious here.
If you're looking to use an Active Bias Controller for the HMC815B then the HMC980LP4E or the HMC920LP5E will be able to bias the RF driver.
