Can I use the gate voltage to pulse HMC994APM5E and HMC1082LP4E on and off (500nS on, 1ms repetition rate)?

Question

Can I use the gate voltage to pulse  HMC994APM5E and HMC1082LP4E on and off   (500nS on,  1ms repetition rate)?

Accepted Answer

Yes, you can do this. Be aware of how much capacitance is on the gate line. Also, the gate voltage should be able to source and sink a little current (sub mA range unless you are taking the amp deep into saturation). Note that an active bias controller such as HMC980 will be too slow for the targeted response time. For more information on the response time of the HMC980's gate voltage output, refer to pages 9-10 of the application note AN-1363 (Rev.B) available at https://www.analog.com/media/en/technical-documentation/app-notes/an-1363.pdf.
