Dual-Mount, Low-Force Gasket

Omega's 99-880-04-20 electrical contact and shielding gasket offers very low compression force, excellent resiliency and superior RF attenuation characteristics. Manufactured from thin gage copper, the part has a low-profile shape that exhibits minimal resistance force. The design of this gasket allows it to be mounted in a clip-on or stick-on configuration offering maximum versatility.

The gasket provides excellent EMI/RFI shielding performance for small gap applications with a dynamic range as small as .07" (1.8 mm). The design allows compression to 25% of its original height, allowing complete electrical contact within a short range of movement.

Omega's 99-880-04-20 beryllium copper shielding gaskets are in stock with a bright surface finish.

Testing Equipment for Shielding Efficiency

Designed for use by EMC test houses and electronic product manufacturers, the CGE03 comb generator emitter from York EMC Services is placed either inside a housing to test its shielding properties by providing a known signal, or used to validate an entire EMC test system as required by ISO17025. It also enables manufacturers to test shielding performance before the electronics are ready so problems can be detected early.

The CGE03 performs these functions with a much wider frequency span -- 900MHz to 40GHz -- than any other similar product. It generates a stable comb of harmonics, which are switchable between 900MHz and 1GHz.

The unit is powered from a bespoke battery pack so that any unwanted effects from inter- connecting cables are avoided. Where size is restricted, the CGE can be powered from an external power supply, reducing its height from 3.5" (90mm) to 1.6" (40mm).

Photo Etched Miniature Parts Manufacturing

Tech-Etch manufactures small, light-gauge metal parts through photo chemical etching, a process that produces intricate components with close tolerances.

Metals that can be etched include Nitinol, Titanium, Tungsten, Molybdenum, Copper Alloys, Beryllium Copper, Stainless Steels, Aluminum, Elgiloy, Niobium, Nickel Alloys, Silver, and Spring Steels, in addition to Polyimide Film. Many of these materials have characteristics that are attractive to the medical industry. Parts range in thickness from .0005" and up. Formed parts are manufactured by combining photo etching for blanking with inexpensive or universal tooling for forming. While providing quick turnaround and low tooling costs, this method produces burr-free parts with intricate and complex shapes. Designs can be proved in preproduction quantities without having to commit to expensive tooling. Laminating, plating, heat treating, and assembly are available in house.

Testing Solutions For RF Conducted Immunity

AR RF/Microwave Instrumentation is offering two complete testing solutions for RF conducted immunity.

The CI00400 (100W, 10kHz - 400MHz) is designed to test to MIL-STD-461D and E CS114, DO160D and E, EN/IEC 61000-4-6, IEC 60601-1-2, EN 50130-4, EN 61000-6-1/2, and EN 55024 standards.

Model CI00250 (75W, 10kHz - 250MHz) provides complete testing solutions to the following standards: EN/IEC 61000-4-6, IEC 60601-1-2, EN 50130-4, EN 61000-6-1/2, and EN 55024.

These systems are fully self-contained in a single rack and include a signal generator, 2-channel power meter, 100 or 75W AR amplifier, directional coupler, and control software. The AR RF amplifier, signal generator and power meter can be used independently of the system; and a larger amplifier can be connected to the system for special needs or if standards change.

Pre-installed software is available as an option. The use of spectrum analyzers and monitoring equipment may also be controlled by the Lab-View-based software that controls the system.

The built-in versatility of the CI00400 and CI00250 test systems makes them a perfect fit for every test laboratory and equipment manufacturer that needs to perform conducted immunity testing.

AR products are backed by the company's "Competitive Edge" warranty.

World's Smallest DAB Radio Module

Frontier Silicon now offers the world's smallest and lowest-cost digital audio broadcast (DAB) radio module (pictured on page 1). The new Capri FS3010, measuring only 27 x 16 x 2.6mm, is a miniature SMT module, which enables it to be fixed directly to the DAB radio system board and avoids the need for connectors. Its small size and high level of integration makes Capri ideal for low-power product applications such as tiny pocket DAB players, MP3 handhelds, PDAs and other portable entertainment devices.

The Capri module is based on Frontier Silicon's Apollo multi-band RF tuner and Kino 2 multistandard DAB and T-DMB digital baseband processor. Complete systems can be built using Capri as a slave module controlled by a host

processor, with several host interfaces available for control and data transport streams, including SPI, SCP, and I2S. The module receives both L-Band and Band 3 broadcasts, enabling worldwide DAB reception.

Apollo measures just 5 x 5 x 0.9mm, making it the world's smallest RF tuner for DAB digital radio reception, and requires very few external components. The Capri module is available now.

USB Support Now Offered with Schaffner Software

Schaffner Test Systems' Compliance 3 emission and immunity test software now supports instruments with a USB interface, allowing users to invest in new, lower-cost instruments that do not require a GPIB (general purpose interface bus) card in the controlling PC. The interface has several advantages. It uses smaller, more flexible cables, has fewer cable length restrictions and enables multiple instruments to be easily connected via hubs.

Compliance 3 is used in many labs in commercial, military, automotive and medical tests. Its open architecture and flexible design make it easy to customize, so that users can incorporate complex hardware configurations, define custom test sequences, write device drivers for virtually any instrument and create unique report formats.

High Bandwidth USB EMI Chokes

Steward has released four new common-mode EMI chokes for applications including USB. The small common-mode chokes provide electromagnetic interference filtering capabilities for workload speeds of 25 to 480Mbit/s. These parts are packaged in the small EIA size of 0805.

Steward's new Series 05 chokes handle bandwidth-hungry applications for USB 2.0, such as video and mass storage devices used on data lines. They will suppress common-mode noise without affecting the integrity of the differential signal.

Low Profile Twist Copper RFI Shielding Gaskets

Ferrishield's low-profile twist series of shielding gaskets were designed for small dynamic range applications where the shield, in its "compressed state," will not extend beyond its uncompressed width dimension. They also can be compressed to a near flat position and still return to their free height. Mounting is simple with the standard Instant Tac adhesive.
