SiGe PA Improves Power Consumption for ISM Band Applications
SiGe Semiconductor Inc. announced the availability of the SE2597L power amplifier (PA) designed specifically for 2.4 GHz ISM band applications. This highly integrated silicon device is the latest PA in SiGe Semiconductor's successful line of discrete 2.4 GHz silicon power amplifiers. Offering an industry-leading combination of high performance and low current consumption, the SE2597L integrates a reference voltage generator and a load-insensitive power detector in a popular 3 x 3 x 0.9 mm 16-pin QFN package.
Designed for use in the 2.4 GHz ISM band including 802.11 b/g/n WLAN applications, the SE2597L is a general purpose fully input matched PA that is well suited for a wide range of applications, including industrial, medical, consumer, embedded PC and enterprise networking access points. Optimized for high performance, it delivers +20 dBm output power at 3 percent error vector magnitude (EVM). Operating from 3.3 VDC supply, the SE2597L consumes only 170 mA at +20 dBm.
"With the release of the SE2597L, SiGe continues its tradition of leading the industry with PAs that combine high performance, integrated reference voltage and our unique load insensitive power detector," commented Jose Harrison, director product marketing, computer and consumer. "This high level of integration simplifies the design and test procedures for our customers, provides high performance in a small footprint and it does all this with low power consumption.
Manufactured using a SiGe BiCMOS technology, the SE2597L is RoHs-compliant and halogen-free. The device integrates a reference voltage generator allowing the PA to be enabled and disabled using standard 1.8 VDC CMOS logic. An integrated power detector provides improved accuracy under mismatch (1 dB of error at 2:1 mismatch), which allows the PA to operate closer to its rated power. In addition, by integrating the input match function, the SE2597L PA reduces the external bill of materials by up to 50 percent.
The SE2597L device is supplied in an industry standard 3 x 3 x 0.9 mm 16-pin QFN package, and it is pin compatible with other 3 x 3 mm discrete power amplifiers. It features external output match for improved performance and lower cost. The device is offered along with applications documentation and evaluation boards. SiGe's customer support is readily available to customers to help with design in and to optimize performance while complying with all regulatory requirements for spurious, harmonics and band edge limits. The SE2597Lis available now and is priced at less than US $0.45 in 10k quantities.
