||A unit of inductance, named after a dead American, Joseph Henry.
||highly-accelerated life test
||The "pressure cooker" of qual tests!
||A method of analyzing circuits with non-linear behavior.
||hetero-junction bi-polar transistor
||A good competitor to pHEMT, and requires only one power supply polarity.
||high density poly-ethelene
||Also known as PEHD in countries such as France, HDPE is number 2 in the recycling categories. Chances are your milk jug is made of it. It is also a useful dielectric, with DK of 2.3 and DF of 0.003.
||high electron mobility transistor
||Developed in the 1990s, provides better microwave performance compared to MESFETs.
||high efficiency particulate air (filter)
||The type of filters used to filter out particles down to 0.3 micron in a clean room.
||hexagonal field-effect transistor
||A trademark of International Rectifier for their MOSFET line.
||heterostructure field-effect transistor
||High-Frequency Structural Simulator
||Ansoft's 3D EM simulation tool.
||Hewlett Packard instrument bus
||Too late to rename it "Agilent instrument bus"
||high pass filter
||A two-port network that rejects signals below a certain frequency band.
||horizontal PIN diode
||Used to describe an antenna pattern.
||"Danger, Will Robinson!"
||Refers to the condition that the LO frequency is above the RF frequency.
||high-temperature co-fired ceramic
||A method of fabricating circuit traces embedded in ceramic.
||Unit of cycles-per-second, named after a dead German. Not to be confused with the dead Austrian who started that rental car company.
