ADF4360-2 Temperature characteristics of output power

Sorry, there is one correction.

× The temperature was changed between -40 ℃ and 125 ℃, but there was a fluctuation of 5.42dB (0.04dB / K).
○ The correct range is -40 ° C to 85 ° C, but there was a fluctuation of 5.42dB (0.04dB / K)

Hi,

I am very in trouble.
Can you ask for an answer?

Hi,

In addition, we will inform you about register settings.
・ CONTROL LATCH → 00F928h
・ R COUNTER LATCH → 000029h
・ N COUNTER LATCH → 010C1Ah

The correction of the question content will be described again.

Please let me know if you need any other information.

Hi Naohisa, 

What is your specifications for output power over temperature? Expected variation for ADF4360-2 is around 3.5-4 dB over -40 to 85 ° C. Additional loss you see may be caused from lumped elements, board or cables.

Hi Kudret,

Thank you for your reply.

The aim is less than 1 dB for the entire system.
There are other active components such as amplifiers, so we plan to reduce them by temperature compensation.
Since the temperature coefficient of a single device was large, this question was asked.

Please let us told if there are any remedies.

Unfortunately, it is not possible to keep output power variation over temperature within 1 dB range
