AWR1642: Power-On Hours

Kei

Part Number: AWR1642

Hello,

Regarding POH written in AWR1642 datasheet, according to the URL below, '100% duty cycle' means continuous RF transmission and if duty cycle is 50%, POH will double.

And so I have a question. If duty cycle is 25%, will POH quadruple?

If there is no RF transmission, will POH be infinite?

Hello ,

At 100% duty cycle the POH is limited by the RF circuits. So If the duty cycle is made half, the POH will roughly double. But beyond that the POH will start getting limited by the digital circuits also. So by making 25% duty cycle the POH will not become 4 times, since the digital circuits are still engaged.

Vivek
