HMC1049 Pulsed operation

Question asked by rubenz on Mar 26, 2018

There is an application for HMC1049 for pulsed input with the following pulse power and durations:

+32dBm for 100ns

Followed by +20dBm for 50us

<-50dBm for at least 285us.

Although the average power (-36dBm) is very low the peak power of +32 dBm for 20 ns is much higher than the specified 18 dBm for 285 us higher by 2 dB.

1. Would  this pulsed  condition  damage the amplifier?

2. Is there any other available data for pulsing this amplifier?

 

Thanks.

Correct Answer

Hi,

 

Based on HMC1049 datasheets, CW maximum input power is 18 dBm.

We have not done any pulse tests therefore we can not guarantee beyond 18dBm of input power regardless of pulse duration.
