3.13 RF Interface

3.13.1 RF Interface Characteristics

The nominal impedance value is 50 Ω. The DC impedance is 0 Ω, connected to GND.
The RF connector is a MMCX (Miniature Micro Connector) type. (See section "Supplier Information", 8.1.2)
MMCX connector characteristics and benefits:
• Standard type
• Small physical size type
• Easy-to-find product
An antenna can be directly connected through the mating connector or using a small adaptor if necessary
(MMCX-SMA for example) (see section "Supplier Information", 8.1.2).
The MMCX connector incorporates a 'snap-on' latching action in order to make connection easier with
excellent RF performance. This type of connector is suitable for the standard ranges of flexible and semi-
rigid cables.

3.13.2 RF Performance

RF performance is compliant with the GSM 05.05 recommendation.
The main Receiver parameters are:
• E-GSM900 Reference Sensitivity = -104 dBm Static & TUHigh
• DCS1800 Reference Sensitivity = -102 dBm Static & TUHigh
• Selectivity @ 200 kHz: > +9 dBc
• Selectivity @ 400 kHz: > +41 dBc
• Linear dynamic range: 63 dB
• Co-channel rejection: >= 9 dBc
The main Transmitter parameters are:
• Maximum output power (E-GSM 900): 33 dBm ± 2 dB at ambient temperature
• Maximum output power (DCS 1800): 30 dBm ± 2 dB at ambient temperature
• Minimum output power (E-GSM 900): 5 dBm ±- 5 dB at ambient temperature
• Minimum output power (DCS 1800): 0 dBm ±- 5 dB at ambient temperature
