T-28 U-Bee zigbee Wirelee Module

Big differences to compare with all of the IEEE 802.15.4 based products in the market are that US-T28 is not a simple RF module but with embedded solution which allows users to implement various kinds of applications. No need to bother the sophisticated development environment and lots of RD chores, simple settings via common PC will be sufficient.

 

Such high level of integration helps to reduce the overall system cost and simplifies the development efforts during the process. In particular, the standard device can also incorporate a wide range of digital and analog peripherals for further developments.

Where there’s situations need to extend the wireless control coverage, a power amplifier (PA) module can be easily adhered to the US-T28. No additional efforts need to be done. US-T28-PA, a radio frequency (RF) front end module integrating a highly efficient and linear one-stage power amplifier (PA), RF switches, a low noise amplifier (LNA) and a band-pass filter (BPF). Using this integrated RF front end module, not only the required board space can be reduced, but also the external components.
