2.4 GHz Transmit/Receive Front-end Module with Integrated LNA

The SKY65336-11 is a high efficiency, 8 x 8 millimeter multi-chip front-end module (FEM) for ZigBee and other 2.4 GHz industrial, scientific and medical (ISM) band applications. The FEM is comprised of a selectable transmit and receive (Tx/Rx) path. The Tx path incorporates a harmonic filter and high efficiency PA which delivers 20 dBm at the module's output port. The Rx path includes a low noise amplifier (LNA) which boasts a total Rx path noise figure of 1.9 dB, including switch loss. Both the Tx and Rx paths integrate baluns to provide differential ports and seamlessly interface with Silicon Labs’ Ember EM250 and EM260 ZigBee™ transceivers.

About the EM250 & EM260

The Ember EM250 system-on-chip (SoC) along with the EmberZNet PRO networking stack is the industry's only true SoC platform supporting the ZigBee PRO Feature Set. The EM250 integrates an IEEE 802.15.4 radio, a 16-bit microprocessor, flash, random access memory (RAM) and peripherals delivering excellent performance at a low system cost.

The Ember EM260 is the industry's first ZigBee network co-processor that combines a 2.4 gigahertz (GHz) IEEE 802.15.4 compliant radio transceiver with a flash-based microprocessor running the EmberZNet PRO ZigBee stack. The EM260 delivers unparalleled flexibility allowing developers to easily add ZigBee networking to their preferred application microprocessor via a fast SPI/UART interface.

The EM250 and EM260 chips are tightly integrated with EmberZNet PRO - The Ember "ZigBee Golden Unit" platform - and are optimized for designs requiring long battery life, low external component count, and a reliable, proven, industry-standard networking solution. Innovative on-chip debugging combined with Ember InSight tools provide developers with the most advanced views into their application and network available in the industry.
