“These devices highlight Skyworks’ growing suite of WiFi solutions designed to address the expanding opportunities in high-performance gateways, access points, smart phones, media, and emerging mobile Internet access platforms,” he added.
The SKY65152-11 (20-pin, 6 x 6 mm) and the SKY65165-11 (16-pin, 3 x 3 mm) are microwave monolithic integrated circuit (MMIC) PAs with superior output power, linearity, and efficiency. This makes them ideal for wireless local area network (WLAN) applications. The high linearity, low EVM and high efficiency of these devices also make them suitable for use in the transmit chain of WLAN access points and modems.
The devices are fabricated using Skyworks’ Heterojunction Bipolar Transistor (HBT) indium gallium phosphide (InGaP) process, which allows for single supply operation while maintaining high efficiency and good linearity.
The SKY65152-11 is a fully-matched PA, incorporating a directional power coupler for accurate power detection, mounted in a multi- chip module (MCM) package
The SKY65165-11 is internally matched at the radio frequency (RF) input, includes integrated power detector, biasing and is mounted in a quad flat no-lead (QFN) surface-mounted technology (SMT) package, which allows for a highly manufacturable low-cost solution.
The SKY65152-11 and the SKY65165-11 are available now.
The SKY65152-11 is priced at $1.58 each and the SKY65165-11 is priced at $1.15 each in quantities of 10,000 devices. Volume production is scheduled to commence in the fourth quarter of this year.
RFMD reveals module designed with Ember
RF6525 Front End Module (FEM) is targeted towards ZigBee-Based Smart Energy and ISM Applications and operates in the 2.4 GHz-2.5 GHz frequency band.
RF Micro Devices announced the availability of it’s highly integrated RF6525 front end module (FEM). The FEM is designed to meet or exceed system requirements of high efficiency ZigBee systems with a minimum output power of 20 dBm. Suitable Zigbee applications operate in the 2.4 GHz - 2.5 GHz frequency band.
Applications supported by the product include smart energy/advanced metering infrastructure (AMI), home area network (HAN), wireless ZigBee home automation, portable battery powered equipment, and general 2.4 GHz ISM band systems.
Designed in collaboration with Ember Corporation to create the RF6525/EM357 reference design, the RF6525 integrates a +20dBm PA with a Tx harmonic output filter in the transmit path, and a low noise amplifier (LNA) with bypass mode in the receive path.
The RF6525 also includes a low insertion loss, high isolation, double-pole double-throw (DPDT) diversity transfer switch and a two-port 50 ohm Rx/Tx integrated balun that simplifies matching and provides balanced input and output signals for both the Tx and Rx paths. In the receive path, the Rx chain provides 11.5 dB of typical gain with only 7 mA of current and an excellent noise figure of 2.5 dB.
The high level of integration and small footprint of 3.5mm x 3.5mm x 0.5mm should reduce customer assembly and material costs and external discrete component count. Coupling RFMD’s RF6525 FEM with Ember’s EM357 should also shorten customer design time and accelerate time-to-market.
Samples and pre-production quantities of the RF6525 are immediately available with
