TīmeklisSteps to transmit an RF command to EM4305 or EM4205 RFID tag 1. Send ‘first stop field’ (mod pin of EM4095 ‘high’ for 32 to 100 RF cycles). a. The 1st field stop duration is application dependent. b. 32 RF cycles is enough for ISO card size tags. c. The high Q tags (e.g.; glass tube animal chips) require up to 100 RF periods – the TīmeklisThis time is short compared with the RF period, it is thus legitimate to assume that the field emission process is instantaneous and occurs in a “quasi static” electric field. With this approximation, the average current emitted in RF regime can be calculated, using Eq. (2): ≈S. C.β2.5.E peak 2.5 Φ exp(−B Φ3/2 β.Epeak) C = 2. 2 ... port hope private school
