Digital Voice and Data Transceiver For LMR and PMR Systems


Can operate on low power and securely provide long-distance digital communication

CML Microcircuits’ SCT2400 is a highly integrated digital voice and data transceiver operates in the 2.4 GHz, ISM band and provides secure communication links over long ranges, up to 12km line-of-sight, but with extremely low power consumption. The SCT2400 integrates a high performance radio transceiver, baseband processing including digital voice and data coding.

Up to 100 mW of output power is achieved while consuming just 10 mA in scan mode, around 52 mA when receiving voice and just 64 mA when transmitting voice. CML’s voice coding expertise and advanced forward error correction maintains clarity and security in long range/low power radio systems such as Private Mobile Radio (PMR) and Land Mobile Radio (LMR). Operating from a single 3V supply, the low power dissipation and small size (10mm by 10mm, 144-BGA package) means it can be used in portable, mobile and wearable products, including fitness trackers, smart clothing and wireless headsets.


This CML transceiver supports digital voice modes that include peer to peer, group call and broadcast, along with an SMS data mode.
