这是今年2月份 freescale在泉州的讲座里的资料。考虑到最近手头比较紧,还有可能很多兄弟姐妹也没有参加这个讲座,所以可能很多人还是没这份资料,所以发在这边呵。
这是我见过的最翔实的射频专业名词的解释。从A到Z,所有的专业单词,不怕你找不到,就怕你想不到呵呵。
RF & Microwave Glossary
'A' Carrier:
The nonwire cellular company, that operates in radio frequencies from 824 to 849 Mhz.
AGC:
Automatic Gain Control - A feedback control circuit which maintains the gain or output power level of an amplifier constant over a wide range of input signal levels.
Airtime:
Time spent on a cellular phone, which is usually billed to the subscriber on a per minute basis.
Alumina (Aluminum Oxide, Al2O3):
Alumina ceramic is used as the substrate material on which is deposited thin conductive and resistive layers for thin film microwave integrated circuits.
AM Noise:
The random and/or systematic variations in output power amplitude. Usually expressed in terms of dBc in a specified video bandwidth at a specified frequency removed from the carrier.
AM-PM Conversion:
AM-PM conversion represents a shift in the phase delay of a signal when a transistor changes from small-signal to large-signal operating conditions. This parameter is specified for communications amplifiers, since AM-PM conversion results in distortion of a signal waveform.
AMPS:
Advanced mobile phone service, the standard for analog cellular telephones.
