MILITARY SPECIFICATIONS

Technical requirements and standards adopted by the Department of Defense that must be met by vendors selling materials to DOD [4].


MILITARY STANDARDS

Standards of performance for components or equipment that must be met to be acceptable for military systems [14].


MILLI

A prefix meaning one-thousandth [1].

MINIATURE ELECTRONICS

Modules, packages, pcbs, and so forth, composed exclusively of discrete
components [14].


MINIMUM DISCERNIBLE SIGNAL

The weakest input signal that produces a usable signal at the output of a receiver. The weaker the input signal, the more sensitive the receiver [18].


MINOR LOBE

The lobe in which the radiation intensity is less than that of a major lobe [10].

MINORITY CARRIERS

Either electrons or holes, whichever is the less dominant carrier in a
semiconductor device. In P-type semiconductors, electrons are the minority carriers; in N-type semiconductors, the holes are the minority carriers [7].


MINORITY CURRENT

A very small current that passes through the base-to-collector junction when
this junction is reverse biased [7].


MIXER

In radar, a circuit that combines the received RF signal with a local-oscillator signal to effectively convert the received signal to a lower IF frequency signal [18].


MODE SHIFTING

In a magnetron, the inadvertent shifting from one mode to another during a pulse [18].
