Skyworks Solutions and Ember recently introduced new solutions for ZigBee applications targeting the growing energy management, home area network and industrial automation markets. The partnership has seen Ember integrating Skyworks’ front-end modules (FEMs) into its ZigBee networking systems.
Skyworks’ SKY65343-11 is an FEM for ZigBee and other 2,4 GHz applications. It contains a 2,4 to 2,5 GHz, high-efficiency transmit (Tx) path and a low-loss bidirectional path. The bidirectional path contains a high isolation Tx/Rx switch and balun for low-noise differential output. The differential output receiver port is also bidirectional and can be used to operate the module in a low-power Tx mode.
The SKY65344-21 operates in the same frequency band, with a bidirectional path which can be used to directly connect the antenna port to a directional RF port. The Rx path contains a high isolation T/R switch, low-noise amplifier and balun for low-noise differential output.
The Tx path in both devices consists of an harmonic filter and power amplifier capable of providing >20 dBm of power at the antenna port. Also included is an internal balun to allow use of differential input signals. Both parts are mounted in a 20-pin SMT package.
The EM300 series ZigBee chips from Ember are an ARM Cortex-M3 based family of system-on-chips (SoCs). The EM351 and EM357 combine a 2,4 GHz IEEE 802.15.4 radio transceiver with a 32-bit microprocessor, Flash memory and RAM with powerful hardware supporting network-level debugging features. The chips are tightly integrated with EmberZNet PRO, Ember’s ZigBee compliant mesh networking software.
The EM351 integrates a programmable ARM Cortex-M3 processor, IEEE 802.15.4 RF radio transceiver, 128 KB Flash and 12 KB RAM, as well as as the aforementioned EmberZNet PRO network protocol stack supporting the ZigBee PRO feature set. In addition, the EM357, optimised for applications that require more memory, has 192 KB Flash and incorporates all the other characteristics and features of the EM351.
