BAR50...
Silicon PIN Diodes
Current-controlled RF resistor
for switching and attenuating applications
Frequency range above 10 MHz up to 6 GHz
Especially useful as antenna switch
in mobile communication
Very low capacitance at zero volt reverse bias
at freuencies above 1 GHz (typ. 0.15 pF)
Low forward resitance
Very low harmonics
