ADRF5144 input power

Product Number: ADRF5144

In ADRF5144 datasheet, I checked the RF input power.

I will operate power 43~44 dBm of HPA at 9~10GHz with RF switch.

Please refer to below sequence,

HPA(43~44dBm) -> ADRF5144(RF1 or RF2 port ) -> ADRF5144(RC_port) -> 42~43dBm.

I worry about absolute or recommend RF input Power limit at Ta25degC

Would you let me know what the absolute and recommend -RF-nput-power-limit is at Ta 25degC?

or Could you recommend better performance things?

Sincerely

Taehwan choi.

  • Hi Zheng.

    Thank you for your detailed reply.

    I am late, I am so sorry.

    I had checked RF input power for pulsed conditions in Table 1, which is 43 dBm max at Tcase = 85degC.
    As your mention for thermal management, if thermal management is good that the temperature directly from the top is 25~50degC, I thought max RF input power is over 43dBm. So, I wonder what Max RF input power is at about 50degC?

    if it is not guaranteed, Can you recommend RF switch over 43dBm RF input power value?

    Sincerely,

    Taehwan Choi.
