HUBER+SUHNER announces the launch of their new QLF compliant QMA attenuator series. Only QLF compliant QMA connectors are guaranteed to be intermateable.

2W QMA Attenuator

HUBER+SUHNER announces a new series of attenuators that employ the Quick Lock Formula (QLF) standard for QMA connectors. The QMA interface is based on the SMA interface dimensions but takes up to ten times less time to mate and demate. QMA connectors have smaller space requirements then SMA connectors allowing increased packing density because torque wrenches are not required. Both of these factors result in reduced cost of ownership. Currently three products are available in 2 watt (125 Peak) power rating with attenuation values of 1, 3, and 10dB. The series operates over a frequency range of DC-18GHz. Additional variants with other attenuation, power, and frequency values will be available later this year. These attenuators are ideal for use in telecommunication systems such as GSM, CDMA, WCDMA, and antenna sharing where attenuation is required. They are also ideal for lab applications where precision attenuation and fast mate and demate time is desired.
