求助关于PEP功率，AVG功率，CW功率

lf8808

我是新手，在资料上看到过PEP功率，AVG功率，CW功率，请问大家这几种表示具体区别在哪里，之间有没有什么换算关系呢
谢谢，功放管计算效率时拿那个计算是怎么考虑的呢？
RF Power Field Effect Transistors
N-Channel Enhancement-Mode Lateral MOSFETs
Designed for Class A or Class AB general purpose applications with
frequencies from 1600 to 2200 MHz. Suitable for analog and digital modulation
and multipurpose amplifier applications.
• Typical Two-Tone Performance @ 2170 MHz:（这个频率是两双音频率的中心频率吗？） VDD = 28 Volts, IDQ =
130 mA, Pout = 10 Watts PEP（PEP是什么含义啊）
Power Gain — 15.5 dB
Drain Efficiency — 36%
IMD — -34 dBc
• Typical 2-Carrier W-CDMA Performance: VDD = 28 Volts, IDQ = 130 mA,
Pout = 1 Watt Avg., Full Frequency Band (2130-2170 MHz), Channel
Bandwidth = 3.84 MHz. PAR = 8.5 dB @ 0.01% Probability（PAR是峰均比吗？0.01％表示什么）Power Gain — 15.5 dB
Drain Efficiency — 15%
IM3 @ 10 MHz Offset — -47 dBc in 3.84 MHz Channel Bandwidth（IM3指什么，和IMD有什么关系？）ACPR @ 5 MHz Offset — -49 dBc in 3.84 MHz Channel Bandwidth
• Typical Single - Carrier N-CDMA Performance: VDD = 28 Volts, IDQ =
130 mA, Pout = 1 Watt Avg., Full Frequency Band (1930 -1990 MHz),
IS-95 (Pilot, Sync, Paging, Traffic Codes 8 through 13), Channel Bandwidth
= 1.2288 MHz. PAR = 9.8 dB @ 0.01% Probability on CCDF.
Power Gain — 15.5 dB
Drain Efficiency— 16%
ACPR @ 885 kHz Offset = -60 dBc in 30 kHz Bandwidth
• Typical GSM EDGE Performance: VDD = 28 Volts, IDQ = 130 mA, Pout =
4 Watts Avg., Full Frequency Band (1805 -1880 MHz)
Power Gain — 16 dB
Drain Efficiency — 33%
EVM — 1.3% rms
• Capable of Handling 5:1 VSWR, @ 28 Vdc, 2000 MHz, 10 Watts CW
Output Power

求高手帮忙！

@2170是双音的中心频点；
pep是峰值包络功率，对调制信号来说这是真正的有用功率，载波功率的放大是浪费功率。
0.01％是概率，指的是有0.01％的概率，峰值功率比均值功率大8.5dB;
IM3是隔道功率与测试载波信道功率的差值，而IMD是一般是双音信号测试时三阶交调和输出单音的差值
