Description
The ML46580S-992 is a Gallium Arsenide Beam Lead Tuning Varactor having a Hyperabrupt junction with a resultant constant gamma characteristic.
The constant gamma, high Q values and the elimination of package parasitics are extremely beneficial for the linear tuning of voltage controlled oscillators at frequencies above 20 GHz.
This device has been tested previously for space application in accordance with the requirements of ESA Generic Specifications PSS-01-608 and ESA/SCC 5010.
High Reliability Beam Lead diodes can be supplied using the same procedures established for chip diodes.
These procedures detailed in M/A-COM control document MP3021-001 incorporate the essential elements of ESA/SCC 5010.
M/A-COM can also provide Gallium Arsenide Beam Lead Tuning Varactor diodes with a constant gamma of 1.
0 and also with capacitance up to 2pF.
The Semiconductor Master Catalogue, available on request, contains detailed information of the following additional Tuning Varactor types many of which are suitable for space application.
