Cellular infrastructures

These 38GHz and 42GHz SMT/WSD chipsets are for cellular radio infrastructure.
Avago Technologies has announced that early prototypes of Avago’s proprietary five-chip family have been manufactured. These target the expanding 38GHz and 42GHz cellular radio infrastructure and backhaul point-to-point radio markets.
Based on market demand and customer feedback, Avago designed the millimeter wave products for high performance in SMT packages.
“Our 38GHz and 42GHz point-to-point radio solution has four primary chips and a wafer level packaged directional power detector,” said Allen Chien, Multimarket Marketing Manager of Avago Technologies. “Our innovative chipset will help cellular operators increase their backhaul capacity to meet the demands of mobile data users.”
The wireless infrastructure market is expanding to meet the increasing data rate and reliable connection demands of cellular customers. Smart phones and other devices require high bandwidth data that must be provided by backhaul solutions. Point-to-point backbone radios carry the high capacity traffic from fibre Points-of-Presence (POPs) to wireless access points.
In some areas of the world, 38GHz (37-40GHz) and 42GHz (40.5-43.5GHz) are licensed wireless infrastructure bands. As new point-to-point radios are designed and installed to increase capacity, many radio manufactures are switching to SMT packages and away from traditional chip-and-wire devices. With SMT technology, radio suppliers can offer lower cost, more compact radios to the market and with shorter design cycles.
The chipset is fabricated using Avago’s proprietary 0.17µm gate Pseudomorphic High Electron Mobility Transistor (PHEMT) process. With 80GHz FT transistors, this process is capable of meeting 40GHz applications needs. Manufactured in Avago’s high yield, high volume, six inch wafer processing facility, the chips are packaged in 5mm x 5mm SMT packages with shipment to be in tape and reel. The manufacturing and test operation is fully automated and capable of supplying millions of chipsets per month.
