Avago develops complete RF front-end solution for Point-to-Point Radio

Avago Technologies, which designs and supplies analog semiconductor devices (with a focus on III-V based products), says that early prototypes have been manufactured of its proprietary five-chip family that targets the 38 GHz and 42 GHz cellular radio infrastructure and backhaul point-to-point radio markets. Based on market demand, the firm designed the millimeter wave products for high performance in SMT (Surface Mount Technology) packages.

“Our 38 GHz and 42 GHz 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 chipset is fabricated using Avago’s proprietary 0.17µm gate Pseudomorphic High Electron Mobility Transistor (PHEMT) process. With 80 GHz FT transistors, this process is capable of meeting the needs of 40 GHz applications. Manufactured in Avago’s 6-inch wafer processing facility, the chips are packaged in 5 x 5 mm 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.

Key features:

  • Four 5 x 5 mm SMT chips cover the 38 GHz and 42 GHz bands: Up-converter, down-converter, power amplifier, and multiplier
  • High directivity power detector in 0402 Wafer Scale Package (WSP)
  • Up-converter with variable gain amplifier (VGA) for 24 dB gain control
  • 20 dB Power amplifier with 1 W output
         -   High linearity with a 36 dBm OIP3
  • Integrated buffer and multiplier 
  • Low noise Receiver/Down-converter: Noise figure under 4.5 dB
