COMPONENTS

Ceramic Filter/Decoupling Capacitor

This ceramic filter/decoupling capacitor utilizes revolutionary X2Y® technology. The design incorporates common shielding electrodes that form a Faraday Cage around the standard capacitor.


The addition of the common electrode creates two matched or balanced capacitors enabling simultaneous line-to-line and line-to-ground filtering. The matched capacitor design also eliminates temperature, voltage and aging differences. This component virtually eliminates parasitic inductance and provides superior filter and decoupling performance, allowing multiple component replacement and space savings on the PC board. The capacitor is available in chip sizes 0603 through 1812 and 1410. Price: 50¢ (1000). Delivery: stock to eight weeks.

Star Point Combiner

The star point combiner principle was chosen to implement a suitable filter combiner to achieve low attenuation loss with acceptable mechanical dimensions in combining the uplink and downlink ranges with the receiving and transmitting ranges in a common antenna field. First the receiving and transmitting ranges of each of the two connections are separated in a two-way star point and routed through the filters. Then they are re-combined in a four-way star point and routed to the antenna. The combiner is made up of four temperature-compensated eight-cavity filters. They are combined in a star point network with strip line technology.

Surface-mount Feedthru

The Bell Pin™ surface-mount feedthru has been developed to work with a lightweight alu- minum or brass housing, easily mounting to the bottom of the package creating true surface mountable parts with increased performance. A SWR rating of less than 1.5 up to 15 GHz and offering true 50 performance, this technique is an ideal solution to costly, heavy Kovar packaging problems. The Bell PIN SMT feedthru is made with a gold-plated Kovar base and center conductor fired in place with low loss corning glass. Advanced modeling techniques were used to achieve a 50 frequency range compared to Kovar SMT housings. Hermetic reliability is exactly that of a round ferrule type feedthru.

TEST EQUIPMENT

Test Portfolio

The model E1966A 1xEV-DO test application provides a bench-top tool for designing access terminals (AT) and helps high volume manufacturers speed production and reduce the risk of returns and recalls. The E1966A improves test times significantly by testing 1xEV-DO ATs at the packet level instead of at the frame level used in cdma2000 receiver testing. At the highest data rate, the 1xEV-DO has up to 16 packets per frame, making packet-error-rate measurements 12 times faster than typical frame-error-rate measurements. The test application also incorporates a new spectrum monitor feature with three independent markers that allow quick and easy visual inspection of relative measurements, which are especially useful for production repair benches, quality assurance testing, and general purpose research and development tasks.
