Telecom Lead America: Fabless analog semiconductor
company GigOptix has released the EXE8602-DNT power detector die for high
capacity wireless point-to-point E-band radios.
The EXE8602-DNT, a small form-factor GaAs MMIC die power
detector, is designed to operate over the 71 to 76 GHz and 81 to 86 GHz
E-band frequency bands for applications requiring power detection over a wide
RF power range.
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 also 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.
Highly desirable features include consistent performance
over temperature and output load variations from the typical 50-Ohm system
impedance. 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.
Padraig O’Mathuna, VP/GM of GigOptix’s RF/MMIC product
line, said the EXE8602-DNT enables E-band radios output power monitoring and
control to best suit the conditions and the modulation scheme being utilized.
E-band offers a much less congested frequency spectrum
compared to existing legacy 6 to 38 GHz mobile backhaul bands along with 13 GHz
of allocated frequency spectrum that enables very economical multi-Gigabit per
second communication links.
EJL Wireless Research, in its most recent report,
forecast E-band point-to-point radio links as being one of the fastest growing
segments in the wireless mobile backhaul market with greater than 100 percent
CAGR to 2016.
