PIN diodes deliver predictable performance in miniature packages

Rohm Electronics has a wide range of PIN diodes for RF-switching and tuner-attenuation applications, which achieve ultra-low distortion and a highly linear ohmic-change characteristic resulting in predictable behaviour.

Further attributes of Rohm’s PIN diodes include low high-frequency forward resistance and low capacitance, to minimise losses. The devices span a range of miniature surface-mount package sizes, ranging from the SMD3 type measuring 1.6mm x 2.9mm x 1.1mm to the recently-introduced 0.6mm x 0.3mm x 0.3mm-high GMD2 package.

The first device to be introduced in the GMD2 package is the RN142ZS, which delivers enhanced signal quality as well as miniaturisation when used as an attenuator or as an RF switch.

 

FEATURES Rated reverse voltage: 30V to 60V Maximum capacitance: 0.35pF to 0.9pF Maximum forward current: 3mA to 10mA
