“By leveraging our technology leadership, integration capabilities and scale advantages, Skyworks is capitalizing on the rising tide of increasing RF content associated with these band- intensive 3G and 4G architectures.”
The EVO 4G features Wi-Fi with instant access for up to five computers, a true high definition (HD) camcorder with HD multimedia interface cable that allows flat screen connections, large 4.3-inch wide video graphics array resolution, a multi-touch screen, Web connectivity that is up to 10 times faster, access to live-streaming video applications, and an 8 megapixel camera with auto focus.
The Android-based Desire HD houses a bright LCD display, Dolby Mobile and SRS virtual sound and is the first to be powered by the new 1 GHz Qualcomm 8255 Snapdragon processor.
The Desire Z features a unique “pop hinge” that opens to reveal a QWERTY keyboard with a variety of shortcuts and two customizable keys for instant access to common functions without the need to open menus.
“Given consumers’ growing appetite for anytime, anywhere connectivity, Skyworks is delighted to be partnering with HTC to support several of their 4G platforms facilitating mobile Internet access,” said Liam K. Griffin, senior vice president of sales and marketing at Skyworks. “By leveraging our technology leadership, integration capabilities and scale advantages, Skyworks is capitalizing on the rising tide of increasing RF content associated with these band-intensive 3G and 4G architectures.”
The SKY77701, SKY77702, SKY77703, SKY77704 and SKY77705 PAMs are fully matched 10- pad surface mount modules developed for wideband code division multiple access (WCDMA) applications. The small and efficient modules pack full 1920-1980 megahertz (MHz) (SKY77701), 1850-1910 MHz (SKY77702), 1710-1785 MHz (SKY77703), 824-849 MHz (SKY77704), and 880- 915 MHz (SKY77705) bandwidth coverage into a single, compact package.
Because of high efficiencies attained throughout the entire power range, the PAMs deliver unsurpassed talk-time advantages. In addition, the devices meet the stringent spectral linearity requirements of high speed downlink packet access (HSDPA), high

The SKY13362-389LF is a GaAs pHEMT single-pole, ten-throw (SP10T) antenna switch with an integrated complementary metal-oxide semiconductor (CMOS) decoder and dual low-pass harmonic filters. The switch has five Tx/Rx ports that make it ideal for any combination of 2G/3G multimode cellular applications.
speed uplink packet access (HSUPA), and long- term evolution (LTE) data transmission with high power added efficiency (PAE). A directional coupler is integrated into the modules, thus eliminating the need for any external coupler.
The SKY13309-370 LF is a pseudomorphic high electron mobility transistor (pHEMT) gallium arsenide (GaAs) integrated circuit (IC) single-pole, three-throw (SP3T) antenna switch operating in the LF-3 gigahertz (GHz) frequency range. Switching between the antenna and transmit/receive (Tx/Rx) ports is accomplished with three control voltages. The low loss, high isolation, high linearity, small size and low cost features make this switch ideal for all wireless local area network (WLAN) and Bluetooth systems operating in the 2.4 – 2.5 GHz band.
The SKY13364-389LF is a GaAs pHEMT SP10T antenna switch with an integrated CMOS decoder and dual low-pass harmonic filters. The switch has four WCDMA Tx/Rx ports, four global system for mobile communications (GSM) Rx ports, and two GSM Tx ports that make the device ideal for cellular handsets and data card applications.
