Κεραία & RF Considerations
-
Each antenna port must not receive signals >10 dBm when active, otherwise permanent damage may occur.
-
Recommended minimum distance between module antennas is greater than the device port spacing; ideally, module antennas should be spaced >2 meters apart.
-
Continuous operation requires proper heat dissipation:
-
CPU/core temperature ≤100°C
-
Casing temperature ≤80°C
-
Μετάδοση ισχύος
-
Measured at room temperature, με 24προσφοράς V, in normal transmission mode.
-
<33 dBm series: Uses DCDC conversion for low-voltage power to the PA; voltage fluctuations do not affect maximum output power.
-
≥33 dBm series: PA voltage follows supply voltage. Increasing supply above 24V to the allowed upper limit (see typical rating table) θα:
-
Increase system power consumption by 10–25%
-
Increase max transmit power by ~0.1 dB for 33 dBm units, ~0.3–1 dB for >33 dBm units
-
-
Σύσταση: For efficiency and heat management, use 24V supply.
Παροχή ηλεκτρικού ρεύματος
-
Do not operate the device above the allowed supply voltage limit.
