Turn on/ turn off time of ADL8121

Question

Hi, 
 
 Can I check what is the turn on and turn/off time of ADL8121

Hey Jac, 
 The turn-on and turn-off time for ADL1821 can be founded within the datasheet, specifically within the apps section "USING RBIAS TO ENABLE AND DISABLE ADL8121.")

To give better idea on how to interpret the plot for ADL8107 enable disable, included plot below. Each vertical solid black line is called a div, division. The M100ns at the bottom of the plot indicates that each vertical line or box would be 100ns per division. Within each division is a sub-division. In this case, 20ns per sub-division. The rise time would 20- 30 ns

To answer your question for ADL8121, the turn-on time would be around 380us.

Hey ppp, 
 Rise data is not available for HMC8413. Another amplifier that might work for you could be ADL8102. Operates above 9GHZ should be around the 100ns range for rise time.

Hello ppp, 
 Update on HMC8413 turn-on time. Included an application circuit used to improve the response time to about 75ns for HMC8413. Removed the RLC network that was slowing down the response time and included 5-ohm resistor to improve stability. This circuit has similar performance to default circuit for HMC8413, but with the added benefits of a faster response time.
