1. We use HMC980 to bias the PA chip HMC943 and HMC920 to bias the PA chip HMC498. We want to switch the HMC980 (HMC920) EN pin about 20ms according to the need, that is, to control the power up and down of PA chip HMC943 (HMC498) through the level of HMC980（HMC920） EN pin every 20ms, is there any risk of frequent control of the EN pin?
2. How long is the response time of PA chip HMC980 (HMC920) controlled in the way of 1?That is, after controlling the EN pin, how long will the PA chip reach the normal working state?
Thanks and looking forward to your reply.
