Description  
TEMEX uses its proprietary technology to m anufacture its Silicon PIN diodes in plastic package.  
This product fam ily is designed for a low cost, m edium to high volum e m arket that m ay be supplied  
in tape and reel for autom ated pick and place assem bly on surface m ount circuit boards.  
The use of this technology elim inates wire bonding on to the chips.  
Applications  
Typical applications include variable RF attenuators and AGC (Autom atic Gain Control) circuits,  
from MHz to several GHz.  
The attenuating Pin diode uses properties of variation of forward series resistance versus the DC  
forward bias current. In order to obtain the best dynam ic range, a single diode attenuator m ay be used  
in series or shunt configuration or designed as a m ultiple diode circuit (T or p circuit), where the device  
m ay be m atched through the attenuation range.  
Note:To reduce the distortion, it is necessary to verify and design with the following form ula:
