REVIEW
DESCRIPTION
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.
