Parameter settings of RF620A for RF640R/RF670R

Operation within the EU, EFTA, or Turkey according to DIN EN 302208 V1.4.1
Note
Limitation of the radiated power according to DIN EN 302208 V1.4.1
RF600 systems that are put into operation within the EU, EFTA, or Turkey (ETSI) can be
operated with an RF620A antenna with a maximum radiated power of up to 2000 mW ERP
(or 33 dBm ERP, 3250 mW EIRP, 35 dBm EIRP).
By adjusting the radiated power of up to 70 mW ERP (or 18.85 dBm ERP, 120 mW EIRP,
21 dBm EIRP), the RF620A antenna gain of 5 dBi and the cable loss associated with the
antenna cable, the radiated power of the reader is correctly configured and the radiated
power at the antenna is not exceeded.
Operation in China
By setting a max. radiated power of 1300 mW ERP (or 31.15 dBm ERP, 2140 mW EIRP,
33.3 dBm EIRP), an RF620A antenna gain of 4.3 dBi (7.3 dBic) and the cable loss
associated with the antenna cable (see table), the radiated power of the reader is correctly
configured.
Operation in the USA, Canada
Note
Limitation of the radiated power to 4000 mW EIRP (36 dBm EIRP)
To meet the FCC and IC requirements, the radiated power may not exceed 4000 mW EIRP
(36 dBm EIRP). Therefore the system must satisfy the following relation:
• Conducted power P dBm of the RF600 reader (< 30 dBm)
• Antenna gain G
• Cable loss a
P(dBm) ≤ 30 dBm - (G
Due to the low antenna gain of 5 dBi and the maximum transmit power of 500 mW of the
reader, the maximum permitted radiated power cannot be exceeded.
