OL2385 low RF Output power issue

Hello,

 

We are using OL2385 transceiver module.

We are getting "6 dB" less power than configured.

So to debug I have following questions.

 

  • What is the  complex impedance that chip should see when it is in transmit mode?
  • I am measuring output impedance at antenna port, but issue is that,  measured impedance is same when chip is power off or Powerd on!
    • What should be the configuration of Chip to measure transmit impedance? 

 

Thanks With Regards,

Rakshit Bhatt
