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.
