WiMOD радио модуль ISM диапазона IMST iM240B

WiMOD радио модуль ISM диапазона IMST iM240B
  • Frequency band: 2405MHz to 2480MHz
  • Operating channels: 16
  • Sensitivity: typ. -101 dBm @ PER3

The iM240B is a compact wireless module for the globally available 2.4 GHz frequency band.

The module has superb HF performance, resulting in a link budget of approx. 104 dB. Accordingly, high ranges (> 500m) can be achieved at a data rate of 250 kbps. The quality of the radio link can be evaluated using field strength measurement (RSSI1). In addition to an IEEE 802.15.4 transceiver and a microcontroller, it features an integrated PCB antenna. Of course you can get the module with a 50Ω port for connecting an external antenna. The iM240B can be soldered directly on the target hardware just as usual SMD components.

The integration of an RF system in a new or existing product is therefore significant simplified, which reduces development time, risk and costs.
