High-gain power amplifiers
Sharp Microelectronics of the Americas has announced the availability of new high-gain power amplifiers for wireless LANs, supporting either 2.4 GHz or 5 GHz single-band or 2.4 GHz/5 GHz dual-band configurations in North America. These new RF components extend communication distances to 1.3 times the range allowed by previous amplifiers, while also offering low current use, high power output and optimized error vector magnitude (EVM).
Sharp developed its advanced 2.4 GHz and 5 GHz power amplifiers to support the growing market for products compatible with Institute of Electrical and Electronics Engineers (IEEE) 802.11a/b/g standards. These include products for home and office networking, entertainment, laptops, PDAs, access points and access cards. They are also suitable for applications that require extended communications distances such as those that support HDTV and streaming video.
Each amplifier comes in a 24-pin package, providing for a migration path to accommodate more advanced power amplifiers over time. By keeping the same package footprint for these components, Sharp customers have the option to use either chipset without having to rework the PCB.
The new line of power amplifiers was designed in an advanced RFIC fabrication process that generates a 15% reduction in current usage compared to previous types, and offers sufficient gain to achieve the required output power and linearity required for WLAN systems at 54 Mb/s. In addition, since these new RF power amplifiers feature embedded power detectors, they require fewer external components, and can therefore reduce board space and the overall bill of materials.

Hand-held spectrum analyzer
Anritsu Company's MS2711D Spectrum Master is a hand-held spectrum analyzer. The analyzer, which covers a specified range of 100 kHz to 3.0 GHz, has a -135 dBm noise floor that makes it effective in measuring the low-level signals used in many of today's wireless systems.

SAW filter for CDMA devices
AVX Corporation has introduced a series of surface acoustic wave (SAW) filters for use in mobile phones. Designated the SF16 series, the line includes a small chip scale package (CSP) type radio frequency (RF) SAW filter. The device measures 1.6 mm × 1.4 mm × 0.6 mm. The new SAW filter is developed and manufactured by AVX/Kyocera. With low loss and high attenuation characteristics, the SAW filter delivers advanced voice quality to complement the latest technologies in mobile phones. As part of the product redesign, AVX replaced the previous ceramic packaging with a “flip-chip” style mounting of the miniature SAW chip. After sealing with a flexible external resin, and lead-free hermetic soldering, the device is protected against mechanical shock and harsh environmental conditions.
The use of a ceramic substrate with its simplification of the chip's complex inner wiring reduces parasitic impedance and enables superior levels of attenuation in high-frequency bandwidths above 3 GHz. Additionally, hermetic sealing with ceramic substrate provides weather resistance and durability.
Typical pricing for the SF16 SAW filter is in the $0.30 range, dependent on volume, with lead times from stock to 12 weeks. Samples are available immediately.
Centurion Wireless Technologies Inc. has unveiled the Centurion GPS antenna for telematics applications. Specially designed to provide high gain Global Positioning System (GPS) coverage for commercial and consumer vehicle tracking applications, the antenna is available in the automotive aftermarket and to original equipment manufacturers (OEMs).

C-MAC MicroTechnology, a Solectron company, has extended its range of frequency control products with the CFPT-125 series, a range of low-cost 7 mm × 5 mm SMD temperature-compensated voltage-controlled crystal oscillators (TCVCXO). The CFPT-125 series features a standard frequency stability of ±0.9 ppm over the temperature range of -20° C to +70° C.
The VCXO can be supplied on standard tape and reel for SMT manufacture. It is designed to withstand a peak reflow soldering temperature of 260° C for 10 seconds, making it compatible with lead-free soldering processes. The crystal resonator used within the TCVCXO is packaged in a separate, hermetically sealed, container. This virtually eliminates contamination keeping aging effects to a minimum.
This customer-driven design provides HCMOS output, operates from a 3.3 V supply and draws typically 3 mA — suitable for low-power applications. The oscillator frequency is adjustable by means of an external control voltage enabling the frequency to be calibrated to nominal after assembly.
The industry-standard ceramic surface-mount format makes the CFPT-125 interchangeable with standard (non-tri-state) clock oscillators (SPXO) enabling one board layout to be used at various stability levels provided a control voltage is connected to pad 1.

All components, including firmware, are integrated into its multichip module design. Development is straightforward: Modules and antennas are simply mounted into place (via hand-solder or surface-mounted with automatic pick-and-place equipment), then powered on. No special host software is required; 1×1s directly appear to the system as cables.
Berkana Wireless Inc. has developed a single-chip CMOS radio transceiver for the GSM/GPRS cellular wireless standard. The BKW9000 transceiver replaces more than 35 discrete RF components with a single CMOS IC and is built on TSMC's 0.18-micron MS/RF CMOS process.
As a result, the BKW9000 features smaller device dimensions and is more cost-effective than ICs fabricated on equivalent BiCMOS and SiGe, the alternative processes for RF chips. Berkana's proprietary design technology can also support multiple RF standards including 3G, GPS, 802.11 and Bluetooth.
