Parthus Announces Agreement with STMicroelectronics for Development of Next Generation Bluetooth(TM) Radio Chip

Co-Developed Radio Chip Combines Low Bit Error Rates (BER) and Ultra-Low Power

Consumption in a Cost-Effective and Compact Design

    DUBLIN, Ireland, April 24 /PRNewswire/ --
 Parthus Technologies (Nasdaq:   PRTH) (LSE: PRH), a leading provider of
 platform-level intellectual property for the mobile Internet, announced today
 a licensing and royalty agreement with STMicroelectronics (NYSE:   STM) for the
 development of a single-chip Bluetooth radio.  The radio combines very high
 performance with low power consumption, ideal for next generation mobile
 devices such as cellular phones or PDAs.
     The co-developed radio chip combines low IF architecture and high levels
 of integration which enables a Bluetooth implementation with a minimum number
 of external components.  In addition, the use of ST's proprietary BiCMOS6
 silicon germanium (SiGe) process results in a cost-effective and compact
 design with very low power consumption and low BERs.  High sensitivity and
 high co-channel and adjacent channel performance make the radio the best
 choice for the highest throughput rates of the Bluetooth standard, while its
 low power consumption makes it particularly suitable for battery powered
 devices, such as cellular phones or PDAs.
     "Bluetooth is a critical technology that extends the pervasiveness of
 wireless communication beyond the mobile phone and into the home or office,"
 said Marie-Helene Sibille, general manager of ST's Wireless Communication
 Division.  "Working with Parthus has enabled ST to accelerate our
 time-to-market and to extend our position as the leading semiconductor company
 for the wireless marketplace.  In essence, the ST/Parthus radio is optimized
 for highly demanding applications that require longer transmit/receive
 distances, but with low power consumption and low bit error rates (BER)."
     The spectral purity of the transmitter allows the Parthus/ST radio chip to
 be used with an external power amplifier in Class 1 Bluetooth radio
 operations.  Also, the chip's flexible digital interface allows it to be used
 with a wide range of baseband processors or digital IPs.  The Parthus/ST radio
 makes it possible to design a cost-effective Bluetooth radio with a high level
 of performance in all applications where the digital IP is embedded.
     "We are delighted to be extending our longstanding partnership with ST
 into the Bluetooth arena, one of the most exciting wireless technologies to
 emerge in the last decade," said Kevin Fielding, president of Parthus.
 "Exploiting ST's silicon germanium technology has enabled us to create the
 highest performing Bluetooth radio on the market.  The design methodology was
 based on the use of the latest system modeling and simulation tools.  This
 methodology made it possible to achieve a high level of performance and low
 power consumption in the first cut of silicon."
