SIM _PRES: SIM card detect-Pin 50.
3.3
RF Interface
The impedance is 50 Ohms nominal and the DC impedance is 0 Ohm.
3.4
RF Connections
There are two possible ways to connect an antenna to the module:
•
The antenna can be directly connected to the module on the “Antenna pad” by using a
spring contact.
•
The antenna can be connected to the module through a coaxial cable. The coaxial
cable is connected to both the “Round pad” and the “Ground pad”.
3.5
RF Performance
RF performance is compliant with the recommendation GSM 05.05.
The main parameters for the
Receiver
are:
GSM850 Reference Sensitivity = -104dBm Static and TU High.
PCS1900 Reference Sensitivity = -102dBm Static and TU High.
Selectivity @ 200kHz: > +9dBc
Selectivity @ 400kHz: > +41dBc
Linear Dynamic Range: 63dB
Co-Channel Rejection: >=9 dBc.
And for the
Transmitter
:
Maximum Output power (GSM850) : 33dBm +/- 2dB at ambient temperature.
Maximum Output power (PCS1900) : 30dBm +/- 2dB at ambient temperature.
Minimum Output power (GSM850) : 5dBm +/- 5dB at ambient temperature.
Minimum Output power (PCS1900) : 0dBm +/- 5dB at ambient temperature.
