The antenna must be connected to the RF interface, implemented as a 50 ohms connector available in 2 different options:
The antenna must fulfill the requirements given below: |
|
Frequency TX |
824 to 849 MHz 880 to 915 MHz 1710 to 1785 MHz 1850 to 1910 MHz |
Frequency RX |
869 to 894 MHz 925 to 960 MHz 1805 to 1880 MHz 1930 to 1990 MHz |
Impedance |
50 ohm |
VSWR |
RXmax 1.5:1 TXmax 1.5:1 |
Polarization |
Linear |
Typical Gain |
0 dBi in one direction at least |
The gain must not exceed 8,4dBi@850MHz and 3,5dBi@1900MHz. We recommend a VSWR max of 1.5:1 although a VSWR max of 2:1 can be accepted without affecting performance and certification. The DC impedance is floating but there is no problem when using antenna that present a short to ground. |
