BASESTATION RADIO USES CONSUMERGRADE HANDSET

Cambridge, UK and Cambridge,
Mass., USA: To support
picoChip’s reference design for
the 3G femtocell market,
Cambridge Consultants developed
a basestation radio based
on a consumer-grade handset
component. The radio extends
picoChip’s reference design for
a 3G home basestation, giving
developers a low-cost implementation
for a global market that’s
expected to grow to 100 million
units per annum within the next
few years.
Femtocell products make it possible
for cellular operators to
counter the competitive technologies
of UMA (Universal Mobile
Access) and VoWiFi (voiceover-
WiFi). It also has the
added advantage of
allowing customers to
use their existing standard
cellular handsets.
The HSDPA/HSUPA-compatible
WCDMA design breaks new
ground by adapting an IC created
for low-cost/high-volume
handset applications to implement
the high-specification
basestation radio. It’s combined
with an architectural split that
exploits the very high computational
performance available in
the picoArray DSP device to perform
the baseband and system
control functions.
The resulting 3G home basestation
design requires just these
two major ICs, resulting in a bill
of materials that meets the
aggressive cost targets needed
for this mass application.
Alternative implementations can
require more expensive carrierclass
radio components, combined
with processing cores
based on both DSP and FPGA
technologies.
The 3G basestation design
supports HSDPA and HSUPA
(high speed downlink packet
access and uplink packet
access) data rates of 7Mbits/s
and 2Mbits/s, respectively.
PicoChip awarded the design
contract to Cambridge
Consultants due to the company’s
experience in designing
radios for highly cost-sensitive
markets, such as 2G, ZigBee,
DECT, and Bluetooth.
Primer tool strives to make
development fun
Geneva, Switzerland: What’s
dubbed as a self-contained,
entertaining, and low-cost development
package, the STM32
Primer for the STM32 Flash
microcontroller family is based
on the ARM Cortex M3 core.
Developed by STMicroelectronics,
the STM32 handheld
evaluation and development
tool is designed to provide a
fun and easy introduction to
the features of the STM32. Its
compact, stylised circular
design, including a window
through which you can see the
STM32, is matched with sample
applications. They include two
games, access to a dedicated
on-line community for sharing
resources and experiences, as
well as a RIDE7 integrated
development environment.
New fab to produce
power devices
Ishikawa, Japan: Toshiba Corp.
and Kaga Toshiba Electronics
Corp. opened the doors to a
semiconductor production fab
based on 200mm wafers at
Kaga Toshiba, a consolidated
subsidiary of Toshiba. The fab
will concentrate on the production
of power devices.
The fab is expected to ramp
up to 60,000 wafers a month,
and capacity may be further
expanded to meet market
growth. Toshiba Group’s semiconductor
business covers three
major product areas: system
LSIs, memories, and discrete
devices. Kaga Toshiba operates
as a key Toshiba Group facility
for discrete devices, carrying
out product development and
front- and back-end processes
for small-signal devices and
power devices.
VMETRO acquires
Micro Memory
Buckinghamshire, England:
VMETRO recently acquired
100% of the shares of Micro
Memory. Micro Memory, a privately
held company with headquarters
in Chatsworth, Calif.,
USA, has provided board-level
products for streaming signal
and image processing, real-time
data acquisition, memory nodes,
and Enterprise Network Storage
for over 30 years. VMETRO
offers products that range from
embedded computing and data
recording to storage and protocol
analysers.
