The K6 canceller has been designed to suppress the interference in a co-located receiver from a neighboring transmitter, even if these two radios operate with no guard bands between them. This radio allows for unprecedented densification and spectrum utilization in every RF environment. The solution adapts in real-time to the changing reflection environment to ensure consistent high isolation between the two radios. It operates over a frequency range from 1.1 to 6 GHz and comes with 5 SKU variants while offering an instantaneous bandwidth of up to 80 MHz. This canceller module suppresses interference signals over 40 dB and has an output cancellation power of -5 dBm. The K6 module integrates two antennas on the transmit side and the receive side while offering support for single input single output (SISO) radios. It also embeds switches that allow for bi-directional signal to support co-located TDD radios. This radio does not require modifications in the front-end radio architecture resulting in better flexibility and usability for various applications. It can be tuned in real-time so that the degree of cancellation is maintained even in the presence of dynamic variations in wireless channels. This canceller module can also be remotely controlled using multiple digital control interfaces such as USB , UART , and JTAG. It requires a single DC supply from 6 V to 12 V and operates over a temperature from -35°C to +70°C.
