    final acceptance test of FCC requirements in production floor

    Thanks Biff, That're exactly the minimum tests we do today. Do you know if It's sufficient for FCC or CE?

    Constant power capacitor discharge

    Exactly, As the voltage goes down the current increaes.

    final acceptance test of FCC requirements in production floor

    Hi all, We tested our product in RF testing Lab and got FCC certfication and FCC ID. Are there any requirements for RF acceptance tests during production?How could I be sure that the device I've tested in external lab now doesn't not exceed FCC limits in mass production. Thanks

    Antenna return loss VS efficiency

    The main idea is clear now, thanks you all. Few more questions please, Are efficiency and return loss relevant for receiving as well? In case of omnidirectional antenna ,what is the technic to measure antenna efficiency? Because that omnidirectional antenna transmits to all directions very...

    Constant power capacitor discharge

    I'm trying to calculate or simulate capacitor charge/discharge behavior while connected to constant power load (DC-DC) and at the same time charged by a battery. (Battery, capacitor and DC-DC connected in parallel) There are two power modes, low and high. Most of the time the load is in low...

    Antenna return loss VS efficiency

    Hi Hadi, The antenna datasheet specifies three paramaters: Impedance =50 Ohm,VSWR= 2.3:1 and return loss =-9dB Does it mean that in perfect impedance matching to 50Ohm the antenna still have reflected power of -9dB? and no matter what it will be impossible to get vswr 1:1?

    Antenna return loss VS efficiency

    Hi, Please hep me with following basic RF questions: What is the different between Antenna return loss and antenna efficiency? What does antenna return loss mean? Doesn't return loss depend on the impedance matching? Thanks
