High linearity Wi-Fi power amp optimises transmission of greater datarates over longer distances, allowing systems to support emerging wireless multimedia applications.
The combination of CSR's BlueCore2 radio and SiGe Semiconductor's PA2423L power amplifier enables system designers to meet all consumer requirements for performance, battery life and cost in systems including cellular phones, PCs, PDAs, PCMCIA cards and access points.
"SiGe Semiconductor's power amplifiers provide an unmatched combination of high power, low current consumption and integration, making them the ideal complement to our BlueCore radios", said Glenn Collinson, cofounder and marketing director, CSR.
"As a result of our collaboration, we have produced leading Bluetooth Class 1 designs, and are continuing our relationship on future product developments".
CSR's BlueCore2 reference design is based on the company's second-generation single-chip Bluetooth radio, which offers twice the output power, half the power consumption, and a dramatic reduction in cost compared to its predecessor.
Also integrated on the reference design are the baseband, microcontroller, Bluetooth software stack, CMOS RF transceiver, and SiGe Semiconductor's PA2423L power amplifier.
Packaged in a 6-lead LPCC that measures only 1.6 x 3.0mm, the PA2423L is the world's smallest fully encapsulated Bluetooth Class 1 power amplifier.
The PA2423L also provides leading performance to ensure high signal integrity in real-world Bluetooth environments.
The device produces +22.5dBm output power with 45 percent power-added efficiency including matching circuit losses, which extends the transmission range, and overcomes antenna and filter losses while meeting Bluetooth 1.1 requirements.
"The PA2423L's superiority in power, efficiency and spectrum re-growth complements the BC02's performance for leading Class 1 Bluetooth products.
This winning combination allows Bluetooth products to meet aggressive market cost and performance targets, enabling accelerated Bluetooth deployment", said Jerry Loraine, vice president wireless business unit, SiGe Semiconductor.
