Question Can the ADL5511 be used for envelope detection in HPA and LPA applications? Answer Yes, the ADL5511 has an envelope bandwidth of 130 MHz and a power detection
range of 40 dB. This makes it feasible…
Question A customer is using the ADL5511 in an AGC loop application, by applying a sine
wave at different power levels using a signal generator and using the Vrms
output pin to measure the output.…
Question I want to integrate ADL5511 RF Detector in my application. Do you have any
information regarding the input S parameters for the ADL5511? Answer I’ve attached the original s11 (converted from…
Question: In the ADL5511 datasheet, pins 6, 7, 8, 12 and 13 are designated as No Connect. Are these pins really no-connect or can I ground them?
Answer: Pins 6, 8, 12 and 13 are not internally wire-bonded…
Question wrt to the ADL5511 datasheet, rev.0. page 19. The formula 4 is incorrect? There
is a 2 in the numerator.
Answer This is being acknowlegde and the 2 in the numerator is incorrect. Should…
Question: The datasheet shows the part working with a single 20MHz LTE carrier but can our part also function for 2 or even 3 carriers? Has anyone at ADI tested this?
Answer: We have not tested the…
Q. The datasheet for ADL5511 shows the output response time when the ENBL pin is pulsed. What do the VRMS and VENV response times look like when VPOS is pulsed on and off.
A. The attached plots show…
Question A customer is building a FSK demodulator with the mark & space frequencies
being 18KHz & 20KHz respectively. They require an envelope detector for the
process, and have chosen the ADL5511…
Question Can you use the ADL5511 with different input carrier frequency signals? Answer Using the ADL5511 with different input frequencies is not a problem. You
basically need to configure the device…
Question What’s the difference between ADL5502 and ADL5511? Answer For the most part ADL5511 is a higher performing part than ADL5502. It has
higher detection range and envelope bandwidth. One nice feature…
