A, 2005-07-05 WWW.Microsemi .COM UM9301/UM9301SM Commercial Attenuator Diode PRODUCT PREVIEW DESCRIPTIONDESCRIPTIONDESCRIPTIONDESCRIPTION The UM9301 PIN Diode utilizes special overall chip geometry with an extremely thick intrinsic “I” region, to offer unique capabilities in both RF switch and attenuator applications. Volume production also makes the diode an economical choice suitable for many commercial low power equipments. The UM9301 has been designed for use in bridged TEE attenuator circuits commonly utilized for gain and slope control in CATV amplifiers. Low distortion and high dynamic range are characteristic of the diodes’ outstanding performance. The UM9301 is also appropriate for switch applications, when little or no bias voltage is available. Frequent applications occur in portable 12 volt-powered communications equipments, operating at frequencies as low as 2 MHz.
