Broadcom has introduced a set of RF front-end FiFEM modules optimized for use in WiFi 7 devices. The modules should combat inter-frequency interference and achieve reduced power consumption.
RF modules are a standard part of routers, smartphones and other connected devices. They convert radio signals into electrical signals that built-in processors can understand and convert into operations.
The Broadcom FiFiem modules, now introduced, are the first RF modules the tech giant is providing for WiFi routers and access points with the new WiFi 7 standard. The modules take care of two important tasks; counteracting interference between the three frequency bands, 2.4 GHz, 5 GHz and 6 GHz, that the new WiFi standard uses and reducing the power consumption of these devices.
Less interference
To reduce the interference between the different WiFi 7 frequencies, especially between the 5 and 6 GHz, the modules have so-called FBAR filters.
In addition, the modules reduce the high power consumption that WiFi 7 devices entail for their frequency usage. According to Broadcom, the new RF modules reduce this energy consumption by 40 percent. This is due to a more efficient power amplifier required for amplifying the radio signals.
Other improvements
Other improvements brought by the Broadcom RF modules include less space required on the circuit boards, which also provides better radio signals.
Broadcom has now sent the first copies of the modules to selected customers for testing.
