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.

Film capacitors

Vishay Intertechnology Inc. has released a new series of compact, lead (Pb)-free electromagnetic interference suppression film capacitors that combine a wide range of capacitance values with pitch sizes down to 7.5 mm. Ideal for filters, power supplies, and mains applications, capacitors in the Vishay BC components 339 X2 series have IEC 60384-14 (second edition) and EN 132400 approvals for X2 suppression. The new 339 X2 series offers capacitance values ranging from 0.001 µF to 4.7 µF with tolerances rated at either ±10% or ±20%.

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. Full span sweeps from 9 kHz to 3 GHz can be performed in </=1.1 seconds, while the sweep speed in zero span can be set from <50 ms up to 20 seconds. The high sweep speed allows intermittent interference signals to be captured with accuracy. The MS2711D's AM/FM/SSB demodulator further improves a user's ability to identify interfering signals.

Another benefit of the analyzer is its ability to tolerate input signals up to +43 dBm without any damage. Complementing this capability is the spectrum analyzer's dynamic attenuation feature, which tracks the input signal level and automatically adjusts the input attenuation level to protect the MS2711D in the performance of high RF signal levels. It also enhances the spectrum analyzer's sensitivity in applications where low-level RF signal input exists. Priced from $6350, the MS2711D is available for delivery in four to eight weeks.

The ENA-L network analyzers are designed to provide the basic capabilities needed for characterization of active and passive components such as filters, amplifiers, antennas, cables and CATV taps and distribution amplifiers. The addition of the ENA-L to the ENA series adds two low-cost models, covering 300 kHz to 1.5 GHz and 300 kHz to 3 GHz. The S-parameter test set options provide the most accurate measurements, while transmission/reflection test set options offer the lowest-cost solutions.

The PNA-L is Agilent's next generation of basic microwave/millimeter-wave network analyzers and provides basic S-parameter measurement capability and frequency-offset capabilities for evaluating frequency conversion devices. These new lower-cost instruments are available in models covering 10 MHz to 20, 40 or 50 GHz. Compared to the 8720/8722 instruments, the PNA-L provides increased performance in nearly every area. For example, the PNA-L has frequency coverage to 50 GHz (vs. 40 GHz), dynamic range at 20 GHz of 108 dB (compared to 100 dB), trace noise at 20 GHz of 0.006 dB (vs. 0.03 dB), and measurement speed of less than 9 microsecond/pt (compared to 200 microsecond/pt).

The Agilent ENA-L network analyzers range in price from $12,300 to $23,500. The PNA-L network analyzers range in price from $62,000 to $98,000.

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.

Temperature-compensated VCXO

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.
