CMT2310A – Sub‑G Transceiver: HOPERF is a high‑tech company headquartered in Shenzhen. The company focuses on wireless RF chips and sensors and offers an integrated value chain from ASIC and MEMS design through packaging, testing, calibration and application support.
With its sub‑GHz wireless solutions, HOPERF serves international markets in numerous countries.
Smart metering is a key prerequisite for the digitalization of electricity, gas, water and heat networks, because consumption data must be captured and transmitted automatically, reliably and with minimal maintenance effort. To achieve this, wireless solutions are required that combine long range, low energy consumption and robust communication even in dense networks.
CMT2310A – Sub-G Transceiver at a glance
The CMT2310A from HOPERF is an ultra‑low‑power sub‑1‑GHz transceiver for the 113 to 960 MHz frequency range and supports OOK, 2(G)FSK and 4(G)FSK modulation schemes. With up to +20 dBm output power, a sensitivity of down to −122 dBm and data rates of up to 1000 kbps, the device is designed for robust and flexible wireless links in smart‑meter networks.
Long battery life and short active times are particularly crucial in smart metering. Here, the CMT2310A offers typical sleep currents from 400 nA, duty‑cycle operation for both transmitter and receiver as well as additional super‑low‑power receive modes to further reduce average energy consumption. This makes it especially attractive for AMR and AMI architectures in which meters have to operate reliably and with low maintenance for many years.
At system level, the transceiver is also tailored to demanding wireless networks. Features such as LBT (listen before talk) and CSMA, high‑precision RSSI, automatic frequency tracking, 128‑byte Tx/Rx FIFO buffers, flexible GPIO and interrupt configuration as well as fast frequency hopping support stable communication in mesh or star topologies. In addition, the CMT2310A supports Wi‑SUN FAN 1.0 and has been PHY‑certified by the Wi‑SUN Alliance, which makes it particularly interesting for modern smart‑meter infrastructures in an international context.
For device development, the high level of integration is another key advantage, as many RF and baseband functions are already implemented on‑chip. As a result, external part count can be reduced while enabling compact, industrial‑grade designs for an operating temperature range from −40 to +85 °C.
Further Applications
Beyond smart metering, HOPERF sees additional typical use cases for the CMT2310A such as home security and building automation, ISM‑band data communication, industrial monitoring and control, remote‑control and security systems, remote key entry and wireless sensor nodes. This makes the transceiver suitable for any application that requires sub‑GHz wireless communication with long range, low power consumption and flexible protocol integration.
With the CMT2310A sub‑G transceiver, HOPERF provides a feature‑ and cost‑optimized product that convincingly addresses the key requirements of modern smart‑meter systems in terms of range, energy efficiency and network robustness.
