Cold Hard Filter Facts To Keep You Out of Hot Water After designing filters for hundreds of customers over 20 years, there are some issues that pop up time after time. Here are a few that can help keep you out of trouble: Don't make filters an afterthought: Include them up front in the design. The result will be reduced design time (and possible eliminate a redesign) and probably better performance. Choose a filter with a sharp cut-off and high isolation: Today's spectral environment places signals extremely close to each other. You'll typically need rejection of more than 40 dB outside the filter's passband. Test your product under realistic conditions: Just because products breeze through EMC testing in the lab doesn't mean they won't cause interference on a corner in midtown Manhattan. Subject them to "real-world" signals and perform thorough EMC testing. It's a lot less expensive than recalling them from the field. Keep packaging issues in mind: Remember that high-power filters are larger, surface-mount filters are the least expensive, and while connectorized filters cost more they are less costly to mount than through-hole types.

Wireless News Backhaul to the Front
Backhaul, the transmission path between cell sites and the network backbone and handled mostly by T1 landline connections, has rarely been in the media spotlight. This is in spite of the fact that about 30% of carrier costs are related to backhaul. However, the coming fourth generation of wireless communications (LTE and WiMAX) is bringing backhaul to the forefront. The massive increases in throughput and the transition to data-centric traffic required by these broadband technologies will make T1s prohibitively expensive and technologically inadequate. There are only two technologies with the potential to replace them: fiber and microwave/millimeter-wave point-to-point radios either singly or together. Ideally, fiber would be the overwhelming choice, since it offers massive amounts of bandwidth, but only 20% of base stations are within the reach of fiber and new "plant" is very expensive. Microwave/millimeter-wave radios, while offering less bandwidth, nevertheless deliver up to 500 Mb/s per channel and can be paired to provide more. So when fiber connections are not available the likely choice will be a combination of both technologies, with microwave and millimeter-wave radios spanning the distance between the base station and the nearest fiber connection. Bottom line: Backhaul is a market to watch and is projected to grow tenfold by 2016. What's New at Anatech Electronics
