Hi there,
ADL5502 is wafer-level chip scale package. Mounted on the board, the top side will be coated and block light, but stray ambient light can get in from the sides and create free carriers in silicon. This causes higher leakage currents in some…
ADL5502 has a low frequency boundary of 450 MHz according to the datasheet. What would be the issues if I operate it around 100MHz? Any hint?
The two ADL5502-EVALZ boards have different behaviors.
We tested the behavior after purchasing 2 ADL5502-EVALZ boards about two weeks ago.
One board (A) seems to be working normally.
However, the other board (B) has an output of about 400mV, regardless…
Hello,
I have question about ADL5502 datasheet P5 "Peak Hold time".
The datasheet has Peak Hole Time.
In this section has "CNTL=high". For peak hold, CNTL should be "Low".
How should I understand the explanation?
…Hello everybody,
A femtosecond laser pulse generates an electrical pulse on a photodiode.
Pulse is gaussian like with a FWHM of 590ps thanks to the rise time of the PD (175ps) - this means a Bandwith of up to 2GHz
The ADL5502 is used for RMS and peak…
Hi,
I'm looking for an RF peak detector in the 200-600 MHz frequency range. (whit hold and reset functions)
The ADL5502 device would have all the needed functionalities, however the lowest input frequency is only 450 MHz.
Do you have any suggestion…
The ADL5502 uses a specifically designed op-amp to accomplish the peak hold function. It is a challenge to come up with a way to implement this function (with similar performance) using an off-the-shelf op-amp.
The peak detector needs to respond to…

Regarding which RMS power detector is best:
Consider one of the linear in Volts-per-Volt detectors…
Take a look at the ADL5502 and the HMC1120. Both have RMS & peak hold detection capability. The HMC1120 has envelope tracking functionality as well.
I'd also look at the ADL5511, which is RMS and envelope detection.
Hi,
I meant the RF detectoor, ADL5502. I would take a look at this and see if it meets your needs. If not then our only ADC option for 2.4GHz will be the AD9625 ADC.

David
