Description:
Cellular and PCS Communications systems are increasingly using point-to-point microwave and millimeter wave radios as the preferred method for interconnecting base stations with mobile switching centers, central offices, and other base stations. Radio links provide system operators with the benefits of rapid installation (no right-of-way issues), network configuration flexibility, and lower operating costs.
As cell installations become denser, the rapid signal attenuation versus distance encountered with higher frequency signals becomes an attractive feature, reducing interference to neighboring installations and allowing greater frequency re-use. This has led to a migration to higher frequencies for short hops. Other trends include the use of higher data rates, an increased concern with reliability, demands for easy installation, and a need for low cost solutions.
This market is seeing a technology substitution as Varactor-tuned solid state sources replace the older Gunn diode solutions. The newer systems offer the advantages of reduced phase noise, greater tuning bandwidth, higher integration and easier use.
Segments include C Band, 15/18 GHz, 23/28 GHz, 38 GHz, and 50 GHz.
Products:
HP provides transceiver and power transmitter components for 23/28 GHz and 38 GHz systems, including modules and millimeter wave Amplifier ICs.
