RF transceiver modules are prevalent in today’s expanding wireless communication markets. WLM101 by TianDe Semiconductor Technology (TST) is a class of high performance RF transceiver modules - helping customers reduce devices power consumption, design size and emphasize their wireless applications.The WLM101 is a compelling solution for digital, cellular, short-range and broadcast applications, offering users the convenience of high- speed digital communication while reducing system costs and power consumption.

The WLM101 is a ready-to-use, high performance RF transceiver module operating in the 2.4GHz industrial, scientific, and medical (ISM) frequency spectrum. It features low power consumption, high efficiency, and minimal size and weight, bringing greater flexibility to various applications. It integrates a wide range of digital functions, including base band, memory, timing, analog-to-digital conversion, amplitude control and modulation, allowing users to configure and communicate via UART, SPI, and I2C protocols.

In addition, the WLM101 comes with a comprehensive suite of features, including a robust transmission rate of up to 250kbps, a spread spectrum communication protocol for enhanced performance and reliability, and a built-in 32K color digital signal processor (DSP) for advanced signal processing. This allows the module to support multiple frequency-hopping schemes, including frequency-hopping spread spectrum (FHSS) and direct sequence spread spectrum (DSSS) operations. It also supports data encryption and authentication protocols such as AES, ECC, and HMAC.

The WLM101 includes an integrated RF transceiver, a 32-bit ARM Cortex-M4 CPU, and a range of analog-to-digital conversion peripherals. Its power-efficient design makes it ideal for low-power wireless applications such as wireless sensor networks, with a maximum power consumption of 2.2W. Its built-in programming peripherals allow users to customize their system for specific application requirements.

Apart from baseband design, the WLM101 offers several signal processing options. It is capable of supporting multiple time-division multiple access (TDMA) schemes, a wide range of modulation techniques such as QAM, PSK and OFDM, and a comprehensive set of data and control modes. Along with its built-in RF transceiver, the WLM101 also supports the Bluetooth Low Energy (BLE) stack, 802.15.4 multi-device networks, as well as frequency-hopping spread spectrum (FHSS) and direct sequence spread spectrum (DSSS) protocols.

Furthermore, the WLM101 utilizes a standard 2.4 GHz operating frequency, allowing it to easily connect to existing 802.11a/b/g/n/ac networks. It also supports multiple topologies, including point-to-point, star, ad hoc, and mesh wireless networks. Additionally, the WLM101 includes a low power, integrated transceiver, with a peak receive sensitivity of ?? dBm. This helps reduce interference and eliminates the need for costly antenna tuning.

The WLM101’s advanced RF transceiver technology and integrated 32-bit ARM Cortex-M4 CPU make it an ideal solution for cost-effective and low-power wireless applications. With its integrated baseband, memory, and analog-to-digital conversion peripherals, the WLM101 can easily be integrated into existing systems and can serve as a single-chip solution for a wide range of wireless applications.
