---|
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. |
---|

TDD | time division duplex | -- |
---|
TDMA | time division multiple access | -- |
---|
TDU | time delay unit | A network that provides switchable path lengths for delaying a signal by a specified time. |
---|
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. |
---|
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. |
---|
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. |
---|
TFR | thin-film resistor | Resistors that are formed using thin-film techniques. |
---|
THZ | terahertz | The region of electro-magnetic spectrum between millimeterwaves and light; 1012 Hertz. |
---|
TIA | trans-impedance amplifier | -- |
---|
TLA | three letter acronym | As in, FBI, EWR, WWW, DOS. Cheer up, there are only 17,576 possible TLAs! |
---|
TM | transverse magnetic | A type of waveform associated with waveguides, requires only one closed conductor. |
---|
TN | equivalent noise temperature | An alternate method of expressing noise figure, often used by scientists with thick glasses. |
---|
TNC | threaded Neill-Concelman | A connector developed a long time ago that you might find on older equipment. |
---|
TOI | third-order intercept | -- |
---|
TPMS | tire pressure monitoring system | A future government mandate to protect fat stupid people from SUV rollovers |
---|
TR, T/R | transmit receive | A transmit receive element, module, or system. |
---|
TRF | tuned radio frequency (receiver) | A radio architecture from the early 20th century. Mostly abandoned when the superhet was developed. |

TVRO | television receive only | -- |
---|
TWT | traveling wave tube | A form of microwave power amplifier. Provides tens of watts to several thousand watts, often with poor noise characteristics but high efficiency. Named after a guy named Wave who was on the road a lot. |
---|
TX | transmit | An abbreviation sometimes used for transmit. |
