Radio Modules

Quad Band GSM Radio Module - GSM-SIM-340D   $49.95 (1-9)  Our Industrial Design Division has used GSM radios from several different manufacturers including SIMCom, Wavetek, Motorola, BENQ, Telit and RIM. And we've found that there are big differences in performance, reliablity and cost. After a lot of testing, we concluded that the SIM340D is the best module we can offer. It is very reliable, has the best performance available and is very cost-effective. And unlike many other modules on the market it is very easy for anyone to mount to a PCB - it also doesn't require any connectors that drive up the cost and reduce realiablity. This module has the highest output power allowed for a GSM radio.
