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 incorpo-
rate the essential elements of ESA/SCC 5010.
M/A-COM can also provide Gallium Arsenide Beam Lead Tun-
ing Varactor diodes with a constant gamma of 1.0 and also with
capacitance up to 2pF.
