Original question:

CC2538: CC2538 RF Transmit

CC2538: RF designs under TELEC with CC2592

Part Number: CC2538
Other Parts Discussed in Thread: CC2592, CC2590

Our customers are limited by the system and assume the use of both CC2592 and CC2538.
We think that the transmission output as close as possible to 10 dbm is possible by combining the settings.
As a matter of fact, CC2592 is necessary to raise 7db to 10db (in order to cover 3db).
Of course there are also issues such as spurious and noise..
Have you experienced any of the above configurations that meet the RF characteristics defined by the Japanese Radio Law?
We are afraid of vague questions, but we would like advice if there are points that require consideration or attention.

Best regards,

    See no problem on using CC2538+CC2592 for such application.

    Hi Katsuhiro,

    I do not know the exact details around TELEC output power and bandedge requirements. If the peak power requirements are for EIRP you may be close to the limit even with 7 dBm output power due to antenna gain.

    That being said, technically you can easily use CC2592 to boost the output power of CC2538 to 10 dBm. If this is the power level you are targeting, CC2590 would be a better option though, as it has less current consumption.

    Regards,
