TACS
|
total access communication
system
|
Analog cell phone standard.
|
|
TC
|
temperature coefficient
or thermo-compression or temperature cycle
|
A type of wirebond employing
heat.
|
| TCC |
temperature
coefficient of capacitance |
|
| TCE |
temperature
coefficient of resistance (CTE is also used) |
An
approximate measure of how a solid expands or contracts over
temperature. |
|
TCR

temperature coefficient
of resistivity
|
An approximate measure
of how a resistor varies over temperature.
|
| TCXO |
temperature-compensated
crystal oscillator |
|
|
TDMA
|
time division multiple
access
|
|
| TDU |
time
delay unit |
A network
that provides switchable path lengths for delaying a signal
by a specified time. |
|
Tn
|
equivalent noise temperature
|
An alternate method of
expressing noise figure, often used by scientists with thick
glasses.
|
|
TE
|
transverse electric
|
A type of waveform
associated with waveguides, requires only one closed conductor.
|
| TE |
test equipment |
|
|
TEM
|
transverse electromagnetic
|
A type of waveform that
requires two conductors, such as coax or stripline.
|
| TFC |
thin-film
capacitor |
Capacitors
that are formed using thin-film processes, often called MIM
(metal-insulator-metal) caps. |
| TFR |
thin-film
resistor |
Resistors
that are formed using thin-film techniques. |
| TFN |
thin-film
network |
A circuit
that is processed on a substrate by depositing layers of metals
(and sometimes insulators), using etching (and sometimes plating)
operations to define features. |
| TFMSL |
thin-film
microstrip line |
This
type of transmission line is often used on silicon RF devices.
Because silicon is not a great insulator, a dielectric layer
such as BCB is deposited, then metal is patterned on top to
define circuitry. |

region of electro-magnetic spectrum between millimeterwaves
and light; 1012 Hertz. |

TLAs! |

|
transverse magnetic
|
A type of waveform associated
with waveguides,
requires only one closed conductor.

often with poor noise characteristics but high efficiency. Named after a guy named
Wave who was on the road a lot.

An abbreviation sometimes
used for transmit.
