  The Module’s functionality is based on WF121: 55-pin Wi-Fi Module from Silicon Labs.

  There are many, but the main advantages using Wi-Fi Module are Ultra highly integrated possibilities of Silabs WF121 Module and strictly and smart ordered Multi-interface connection, Named “MikroBUS” – pioneered By Mikroelektronika.   

  The description of the Wi-Fi 6 Click is limited to overviewing the Highly Integrated Silicon Labs WF121 Wi-Fi Module.

DIAGRAM 1.  Internal Blocks – Diagram

WF121 Module Integrates the following stages:

  • 80 MHz Microchip 4KMIPS 32-bit Micro Controller with 20 Mbit/s SPI, 10-bit ADC
  • Shared 8 MHz Oscillator,
  • Wi-Fi Chipset with 26 MHz Quartz oscillator,
  • 3.3V on-module integrated Voltage Regulator,
  • Bluetooth co-existence with Wi-Fi on 2.4 GHz Band with Antenna switching option to avoid mixed transmission and interferences,
  • For sleep timing of watchdog circuitry, the module has two integrated RC oscillators – one into the WiFi chipset and another one into the CPU.

WF121 Interfaces:

  • UARTs – 2 pcs.,
  • Analog Inputs,
  • GP-I/O,
  • SPI – 4 pcs.,
  • I2C – 1 pcs.,
  • USB, 
  • Ethernet – requires external PHY Media interface 1 – pcs.
  • MCU Programming Interface 1 set,
  • RF Debug Interface. – 1 set.

2.4GHz Band, 802.11 Specifications – Radio Description:

RF Emission Regulatory:

   Integrated Module WF121 works on the IEEE 802.11d standard. That means the hardware select the free channel via the settings and information available from the domain. In the opposite case, the channels are chosen by the FCC Channel List description.

 

Wi-Fi Receiver Path:

   The receiver uses direct conversion principle. Enough out-of-band blocking ratio of the Low-Noise Input Amplifier and cascading  baseband filters of high-order provides the highest receiver selectivity by the side channels, and, nonproblematic work in near distance to GSM cellular phone Power Amplified Transmitters. That allows a minimizing effect by the inner modulation distortion and in-band interferences.

 

Wi-Fi Transmitter Path:

   The transmitter is working on the direct_IQ_modulating_principle. The special integrated digital baseband hardware is used to reduce IQ modulator distortions.

   An another optimization is the transmitter output power in relation to a modulation settings.

Wi-Fi internal PA { Power Amplifier }:

  The Avialable Maximum PA output power is:

  • +15dBm for IEEE 802.11g/n , 
  • +17dBm for IEEE 802.11b .

  The module’s PA gain is internally compensated and practically is not dependent on the oscillator frequency’s “jitter and thermal drift” related to random changes of powering voltages value and ambient temperature.

  The Device is suitable for many hardware applications:  

  • RFID scanners,
  • laser scanners,
  • PoS_Terminals,
  • Internet audio streaming devices, and etc
