工程师:
您好!请问这款对数放大器的Response Time参数是指什么意思呢?
如果我需要放大俩个连续的脉冲信号,这俩个信号如图,这款对数放大器是否可用呢?
谢谢!
AD8319 - Can inputs be driven differentially with INHI and INLO by means of a 100 ohm differential source?
Q:
I want to increase the slope of the AD8319 log amp. Is there a formula to cacluate the resistor values needed?

Hi nirbhay100,
You might consider AD8317 or AD8319. Slope magnitude and polarity are not what you want, but that's easily fixed with an output op amp.

Q.
The datasheet for the ADL5902 RMS detector shows only limited data above 5.8 GHz but the data sheet front page says it works up to 9 GHz. Can it really operate above 5.8 GHz?

Question: RMS detectors with a Linear-in-dB transfer function such as AD8362, AD8363, AD8364, ADL5902 and ADL5906 produces a peaking in detection voltage when driven by RF Bursts when there is no rms averaging capacitor present. Adding an external rms…
AD8318 AD8319的带宽可以达到 140MHz,还有其他一些 放大器
Q.
How can I get the rms detector to accurately detect the power during a pulse modulated signal input?

When a device appears to fail, it looks like its output is very high (about -2.66 dBm instead of -6.37 dBm). Do you have an AGC circiut connected around ADL5331 similar to Figure 19 in the datasheet. Is it possible that this AGC loop is somehow breaking…
We have a couple of applications notes available on our website, CN-0050 (ADL5330, AD8318) and CN-0082 (ADL5331 and AD8319), that deal with this problem. I'm just using these for reference, as they operate in the 1GHz to 2GHz range, lower than what you…
