GigOptix Inc. has introduced a power detector die for high capacity wireless point-to-point E-band radios. The EXE8602-DNT is a small form-factor GaAs MMIC die power detector designed to operate from 71-76GHz and 81-86GHz E-band frequency bands for applications requiring power detection over a wide RF power range, stated the company.

Features of the device include consistent performance over temperature and output load variations from the typical 50? system impedance. Operating with very low DC power consumption, the MMIC produces reference and detector output voltages that can be compared to determine the RF power and which can be further processed to provide RF power in decibel units. The MMIC provides high-capacity-radio manufacturers with an E-band power detector featuring low insertion loss, flat frequency response over each band and high RF power dynamic range with excellent sensitivity. The detector may be used to monitor transmitter operation, or to enable closed-loop control of the transmitter's output power to ensure consistent operation.

"We are very excited to add the EXE8602-DNT power detector to GigOptix's growing portfolio of E-band solutions," noted Padraig O'Mathuna, VP/GM of GigOptix's RF/MMIC product line. "The EXE8602-DNT enables E-band radios output power monitoring and control to best suit the conditions and the modulation scheme being utilized. In light of the growing demand for mobile data due to the advent of cloud computing, the migration of data services to the web and with the mass adoption of smartphones and tablets, E-band offers a much less congested frequency spectrum compared to existing legacy 6-38GHz mobile backhaul bands along with 13GHz of allocated frequency spectrum that enables very economical multiGigabit per second communication links. Indeed we believe that speeds of 10Gb/s and beyond commonly seen in optical interconnects will shortly be enabled in metro areas by E-band links."
