Germanium Tunnel Diodes

MACOMs MTD series of Planar Back (Tunnel) Diode Detectors include a variety of options for your commercial and broadband applications. Commercial products operate between 0.5 to 14.5 GHz and offer low temperature drift, high sensitivity, low VSWR, and excellent flatness.

MACOMs MBD series of Planar Back (Tunnel) Diodes are fabricated on germanium substrates with passivated, planar construction and all gold metallization for reliable operation up to +110 ºC. Unlike the standard tunnel diode IP is minimized for detector operation and binned in five values offering varying degrees of sensitivity and video impedance.
