| SAW filters in CDMA mobile communication networks
|
1999-09-09 |
| Surface Acoustic Wave (SAW) filters are used in the intermediate frequency (IF) filtering stage for both the Code Division Multiple Access (CDMA) handset and infrastructure. They are preferred over other types of filter technologies because SAW filters demonstrate high performance yet low cost and small size. This paper describes the evolution of SAW designs to meet the challenging demands of reducing the size and cost for CDMA IF filters |

| SAW and MWC filters - key components for mobile terminals and base-stations
|
1999-09-09 |
| SAW and MWC devices are key components in modern electronics, especially in modern wireless communication systems. By keeping in pace with the rapid development of wireless technologies, newer and better SAW and MWC devices matching novel market demand will be invented and fabricated with lower insertion attenuation, more stable and wider bandwidth filters, or higher frequency devices than possible. This paper describes the SAW and MWC filter for these development applications |

| Taking new stabs at programmable analog
|
2000-03-01 |
| Programmable logic has some traditional advantages over ASIC design. The gate count of FPGAs approaches that of custom circuits. FPGAs can be programmed—and re-programmed—out in the field, enabling fast time to market. ASICs, in comparison, need careful attention to layout and fabrication technology. It can take anywhere from six weeks to two years (depending on the complexity of the circuit) to get an ASIC working properly. |

| The future of mixed-signal design
|
2000-02-01 |
| I hear two contradictory things regarding mixed-signal IC design. One set of voices says the systems-on-chip (SoC) of the future will be large mixed-signal systems, and the proportion of these being built will double from about 33 percent currently to 66 percent by 2005. The other set of voices says everything will be big digital chips constructed in ever-deeper submicron CMOS, in that the ASICs of the future will use as many 15 million logic gates, but that the analog and mixed-signal circuitry will be left off-chip. |
