Power amp covers both Bluetooth and Wi-Fi
The SE2520L from SiGe Semiconductor is a linear 2.4GHz power amplifier that is fully compliant with both Bluetooth 1.1 and IEEE 802.11b specifications.
Mobile WiMAX power amp outperforms standards
PA delivers more than 20% efficiency at +25.5dBm output power while operating at 3.3V - the highest performance available while meeting worldwide spectral mask requirements.
The designs are supplied in PCI and MiniPCI card formats that enable cost-effective broadband wireless capability in desktop and laptop computers, access points, handhelds and PDAs.
"We are very pleased to be working with a leader like Broadcom", said Jim Derbyshire, President and CEO, SiGe Semiconductor.
"This relationship underscores our ability to supply world-class technology, and serves as a major step in realising our vision to enable wireless enterprise access across home, office and public access configurations".

High linearity Wi-Fi power amp optimises transmission of greater datarates over longer distances, allowing systems to support emerging wireless multimedia applications.
WLAN front ends shrink for portable appeal
Complete 802.11a/b/g/n WLAN RF front-end modules provide all the functionality required between the transceiver and the antenna in dual-band Wi-Fi systems.
The IEEE802.11b standard, sometimes referred to as Wi-Fi, specifies wireless enterprise network access with datarates up to 11Mbit/s in the 2.4GHz unlicensed frequency band.
The technology is rapidly gaining acceptance in small business, home, and public access applications, which benefit from the technology's ability to extend broadband connectivity to mobile devices.
The reference design enables OEMs to reach new levels of stability, since the underlying circuitry is designed specifically to enhance immunity to noise in the crowded 2.4GHz frequency band.
This is achieved in part through the use of SiGe Semiconductor's SE2520L power amplifier.
Part of SiGe's RangeCharge product line, the SE2520L is capable of operating at a duty cycle of 100%, and delivers up to +20dBm of linear output power with an adjacent-channel power ratio (ACPR) of less than -30dBm per 100kHz.
The device further enhances performance through reduced power consumption; operating at 110mA, the current consumption is 50% lower than alternatives.
This drives down power dissipation, thereby improving stability and performance over a full temperature range of -40 to +85C.
"We are pleased to work with SiGe Semiconductor in providing power amplifiers for our 802.11b wireless LAN products.
Their products demonstrated solid stability, range and power consumption", said Ali Hariri, Product Line Manager, WLANs, Broadcom.
"The combination of SiGe Semiconductor components and our technology delivers the right price and performance that our customers demand".
SiGe Semiconductor's SE2520L power amplifier interfaces directly to Broadcom's WLAN chipset.
Broadcom's BCM2051 2.4GHz direct conversion radio and the BCM4301/7 baseband processor form an all-CMOS radio/MAC for IEEE802.11b applications.
The direct conversion radio design minimises cost, number of components and footprint, while improving reliability and manufacturability.
At the back end, the media access controller (MAC) provides hardware-based security that meets consumer requirements across all market segments.
The reference designs are available now directly from Broadcom, supplied with all of the software, firmware and hardware required for design and manufacture.
SiGe Semiconductor's SE2520L is available now, in 100k quantities.
The SE2520L is part of SiGe's RangeCharger product line that also includes the SE2522, SE2522B and SE2529, providing a complete suite of power amplifier solutions for the 802.11 b/g market.
