These couplers can be manufactured with any Graded Index fibre type such as GI50/125µm or GI62.5/125µm with directivity as high as >50dB. In case of high-power UV applications, additional to high ...

High directivity is a great advantage to minimise the light that can directly pass from the injection port to the output port. Also, the insertion loss from port 1 to port 2 is < 6.5dB with a total ...

Rated for use from -40° to +85°C, the wideband, high-directivity couplers are also 100% tested for electrical parameters and visual characteristics. AVX Part Number: Coupler ...

We are developing a new microphone system with sharp directivity, and NHK recently employed it in its relay broadcast of the "Lake Biwa Marathon," held in March (Picture 1 and Picture 2).

Problem In STAR Antenna Systems, isolation tends to be sensitive to the imbalances in the feeding network and to the asymmetries in the antenna geometry. New configurations that can achieve higher dB ...

The main characteristics of ultrasonic sensors for rear sonar are directivity, ringing time, sensitivity and sound pressure. Directivity of an ultrasonic sensor corresponds to the size and shape of ...

Dr. Evert Start from Duran Audio.The What Else: In 2000, Dr. Evert Start from Duran Audio published a paper on Digital Directivity Synthesis at the IOA’s Reproduced Sound Conference in the UK. DDS is ...

Posted August 23, 2014 | Reviewed by Devon Frye The concept of non-directivity can be confusing. In this short article, I will describe what is meant by non-directivity and what it does not mean.
