SKY65337-11

2.4 GHz Transmit/Receive Front-end Module

Please note: SKY65337-11 is being discontinued and is not recommended for new designs.

Skyworks SKY65337 is a high-efficiency, front-end module (FEM) for ZigBee and other 2.4 GHz ISM band applications. The small, 8 x 8 millimeter multi-chip module (MCM) contains a 2400-2500 MHz high-efficiency transmit path and a low-loss bidirectional path. The bidirectional path can be used to directly connect the antenna port to a directional RF port.

The SKY65337 footprint is comparable to the SKY65336, with the LNA removed for applications which require lower cost. The Tx path delivers +20.1 dBm of high efficiency output power, while balanced input and outputs ports have been provided to connect to 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.
