Description

The SKY74210 Helios™ WEDGE transceiver is a compact,

multimode device that supports multiband EDGE and High-Speed

Packet Access (HSPA) mobile handset applications. Designed with

high programmability, the device can be configured to perform

optimally in various modes while sharing the same circuitry.

The SKY74210 eliminates the requirement for interstage receive

and transmit Surface Acoustic Wave (SAW) filters by using

Skyworks innovative direct conversion/very low Intermediate

Frequency (IF) receive architecture and direct conversion transmit

architecture. A set of six-wire, high-speed serial ports provide the

baseband interface (DigRF v3.08 3G compliant).

The direct conversion/very low IF receive architecture eliminates

the need for IF processing and costly SAW filters. Skyworks

innovative circuit design makes it possible to eliminate the

interstage filter, commonly required in WCDMA mode to reduce

the transmit signal. This approach effectively allows the receive

chain to be shared by both EGPRS and WCDMA modes. A second

on-chip receive path is provided to enable diversity operation,

which allows High-Speed Downlink Packet Access (HSDPA),

category 10, data communication.

The direct conversion transmit architecture also allows EGPRS

and WCDMA modes to share the same path. The needed noise

floor is accomplished without using interstage transmit SAW

filters in either mode. Drivers are provided to allow the use of

separate EDGE and WCDMA PAs for optimized efficiency.

The SKY74210 is intended to be combined with selected

components from the Intera™ family of Front-End Modules

(FEMs). The resulting subsystem forms a complete radio solution

that saves significant space, cost, and design cycle time while

providing improved performance.

The SKY74210 is fabricated using 0.13 µm RF CMOS technology

and is available in a compact, 7 x 7 mm Land Grid Array (LGA)

package. A functional block diagram of the SKY74210 Helios

WEDGE transceiver is shown in Figure 1.
