• 0.5dB may be considered as a maximum value for loss between the Wireless
CPU
®
and an external connector.
• In order to maintain the RoHS status of the Wireless CPU
®
, Wavecom
recommends that
lead-free solder-wire and flux be used for Wireless CPU
®
assembly on the motherboard and RF cable, assembly on the Wireless CPU
®
.
Example:
• Solder-Wire: Kester 245 Cored 58 (Sn96.5Ag3Cu0.5)
• Flux: Kester 952-D6
3.21.2 RF Performance
RF performance is compliant with the ETSI recommendation ETSI TS 151 010-1.
The main parameters for a GSM receiver are:
• GSM850 Reference Sensitivity = -104 dBm Static & TUHigh
• EGSM900 Reference Sensitivity = -104 dBm Static & TUHigh
• DCS1800 Reference Sensitivity = -102 dBm Static & TUHigh
• PCS1900 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
And for Transmitters:
