# Is Gain Block can be used a Power Amplifier

I have chosen 2 datasheets of MMIC Power Amplifier:

1. HMC311ST89 MMIC AMPLIFIER – DC-6GHZ -16db Gain
2. HMC637ALP5E – DC-6GHZ – 13db Gain

My intention is to use the 1st one as Power Amplifier. I was wondering whether I am going right because the 1st one description is GAIN-BLOCK whereas, the 2nd one is mentioned as Power Amplifier as per the respective datasheet.

• You need to look at the 1dB compression point (or, alternatively, to third order intercept point) spec in the datasheets in order to make a decision. – Enric Blanco Jun 28 '17 at 9:58
