PDF-4E

      The PDF-4E series is designed as 0° power dividers / combiners.
      It has five features.The first one is about its frequency which would be from 50KHz to 2GHz.The next one is that it would be 4-way.The third one is uniform phase & amplifier bal.The next one is that it would have low insertion loss.The last one is hi-rel herm. flatpack.That are all the features.
      Some general specifications have been concluded into several points as follow.The first one is about its couling which would be -6dB nom.The second one is about its impedance which would be 50 nom.The third one is about its internal power dissipation which would be 50mW max.The fourth one is about its weight, nominal which would be 0.32 oz. (9g).The last one is about its operating temperature which would be from -55 to +85°C.
      It should be noted that this series contain 4 model.For example of PDF-4E-20, its frequency range would be from 50KHz to 40MHz.Its isolation would be min 30dB and typ 35dB.Its insertion loss would be max 1.0dB and typ 0.6dB.Its amplitude balance would be max 0.2dB and tyo 0.1dB.Its phase balance would be max 2° and typ 1°.Its VSWR input/output would be max 1.3:1 and typ 1.2:1.Its input power would be 50mW.And for example of PDF-4E-50, its frequency range would be from 2MHz to 100MHz.Its isolation would be min 30dB and typ 33dB.Its insertion loss would be max 1.0dB and typ 0.6dB.Its amplitude balance would be max 0.2dB and tyo 0.1dB.Its phase balance would be max 2° and typ 1°.Its VSWR input/output would be max 1.3:1 and typ 1.2:1.Its input power would be 1W.For example of PDF-4E-250, its frequency range would be from 10MHz to 500MHz.Its isolation would be min 25dB and typ 30dB.Its insertion loss would be max 1.25dB and typ 0.8dB.Its amplitude balance would be max 0.2dB and tyo 0.1dB.Its phase balance would be max 3° and typ 2°.Its VSWR input/output would be max 1.3:1 and typ 1.2:1.Its input power would be 1W.And so on.For more information please contact us.
