|
ICP
|
Insane Clown Posse. No,
just kidding, inductively-coupled plasma
|
A musical group that you
don't want your daughter to be a groupy for? actually, a great
way to etch via holes in GaAs substrates.
|
| ID |

The
channel current in an FET. |
| IDSS |
saturated

people think this should be abbreviated"SDSC" |
| IEC |

|
|
IEEE
|
Institute of Electrical
and Electronics Engineers
|
A stuffy organization
that many people join to get a good group insurance rate.
The subgroup MTT-S publishes a lot of excellent but hard-to-read
microwave-related papers.
|
|
IF

intermediate frequency
|
The output frequency of
a down converter.

The
difference in magnitude of observed during two-tone IMD measurements. |
|
IMPATT
|
impact avalanche and
transit time
|
A nearly forgotten diode
technology that offered great promise for supplying high power
at millimeter wavelengths.
|
| InP |

Not to be confused with
what that Chinese engineer says every time you blow up one
of his FETs.

categories for your stupid coworkers (be sure to always use
the proper term!)
Idiot (IQ 60-80)
Imbecile (IQ 40-60)
Moron (IQ <40)
|
|
I-Q

|
A mixer that removes
the image frequency contribution from the IF.

The
best possible grounding scheme for power FETs, usually required
2-mil substrates. |
