Diodes
PIN diode
RN739F / RN739D
RN739F / RN739D
!Applications
VHF / UHF band variable attenuators and AGC
!Features
1) Multiple diodes in one small surface mount package.
(UMD3, SMD3)
2) Low high-frequency forward resistance (rF) / low
capacitance (CT).
3) High reliability.
!Construction
Silicon diffusion junction
