I'd like to know if the HMC943APM5 >1.5 W (34 dBm), 24 GHz to 34 GHz, GaAs, pHEMT, MMIC, Power Amplifier can be biased with the HMC980LP4E high current active bias controller? In the first instance I propose using the eval board of each device - is that feasible?
The HMC980LP4E can bias HMC943APM5 up to 1.6A maximum, however IDD need to be set higher than 1.6A in order to support higher output level at higher RF input drive. Below here is plot from HMC943APM5 datasheet showing constant gate voltage bias where IDD increases with RF input power. As an example, in order for HMC943APM5 to reach output power of 32dBm, IDD will need to be set to 1.8A under constant current bias.

David
