Enhanced WiFi 6E and WiFi 7 coexistence filter products
High speed data transmission and requirements for low latency demand implementations of narrow RF multi-channel designs and low interference with coexisting bands, in accordance with WiFi 6E and WiFi 7 / IEEE802.11ax standards. To address this Johanson Technology has announced a tighter rejection 5.5 GHz bandpass filter and a 6.1 GHz dual-band rooftop WiFi 5 and WiFi 6E bandpass filter supporting WiFi 5.5 GHz as well as WiFi 6E and WiFi 7 GHz bands.
The 5.5 GHz bandpass filter, in EIA 1812 (4.5 x 3.2 metric) size and operating frequencies of 5.1 GHz through 5.8 GHz (part number 5500BP44A0700), offers a 50 dB attenuation with a coexisting 6 GHz WiFi band.

The 6.1 GHz SMD filter, in EIA 0603 (1.6 x 0.8 metric) size and operating frequencies of 5.17 GHz through 7.125 GHz (part number 6100BP14A1995), offers a 2 GHz bandwidth solution with 0.9 dB insertion loss suitable for highest antenna power transfer demands.
Johanson Technology 6.1 GHz coexistence bandpass filter supports WiFi 5.5 GHz and WiFi 6E,and WiFi 7 GHz bands.
At the beginning of the year, Johanson released two cost effective differential to single ended baluns for the 5 GHz and 6 GHz bandwidth spectrums (WiFi 6E and WiFi 7, IEEE 802.11ax, 802.11be). Both have an operational frequency of 4900 to 8500 MHz with two impedances, p/n 6750BL14A0050 (1:1 or 50 single ended to 50 ohm differential) and p/n 6750BL14A0100 (1:2 or 50 single ended to 100 ohm differential) to cater to various chipsets’ impedance matching.
With the increased need for low-latency, multi-point, and faster speed wireless routers, these filters exhibit a wide passband with a reduced footprint such as EIA 0603 (1.6- x 0.8-mm) for small form factor products such as VR headsets and portable HD video streaming. These two baluns work great for UWB as well. Automotive AEC-Q200 versions available upon request.
