2.1 Key Features at a Glance

Feature Implementation

General

Frequency bands Quad band: GSM 850/900/1800/1900MHz

GSM class Small MS

Output power

(according to

Release 99, V5)

Class 4 (+33dBm ±2dB) for EGSM850

Class 4 (+33dBm ±2dB) for EGSM900

Class 1 (+30dBm ±2dB) for GSM1800

Class 1 (+30dBm ±2dB) for GSM1900

Class E2 (+27dBm ± 3dB) for GSM 850 8-PSK

Class E2 (+27dBm ± 3dB) for GSM 900 8-PSK

Class E2 (+26dBm +3 /-4dB) for GSM 1800 8-PSK

Class E2 (+26dBm +3 /-4dB) for GSM 1900 8-PSK

The values stated above are maximum limits. According to

Release 99, Version 5, the maximum output power in a multislot

configuration may be lower. The nominal reduction of maximum

output power varies with the number of uplink timeslots used and

amounts to 3.0dB for 2Tx, 4.8dB for 3Tx and 6.0dB for 4Tx.

Power supply 3.3V to 4.5V

Ambient operating

temperature according

to IEC 60068-2

Normal operation -30°C to +75°C

Restricted operation -30°C / +85°C

Physical Dimensions: 33.9mm x 55mm x max. 4mm

Weight: approx. 8.5g

RoHS All hardware components fully compliant with EU RoHS Directive
