• ADL5243 Datasheet


    I might be mistaking but in the Datasheet of the ADL5243 (https://www.analog.com/media/en/technical-documentation/data-sheets/ADL5243.pdf) on page 26 ff. the values of the Resistor R12 are given in nH instead of Ohm. I was wondering what the correct…

  • ADL5243

    I am using ADL5243 VGA,for amplification and I designed the circuit as mention in the datasheet,using the loop configuration at 2.63 GHz, and for e.g.,if we apply the input power -10dBm,2.6GHz signal from  RF generator,the output should be amplified…

  • adl5243

    Hi All,

    I am planning to use the ADL5243 amplifier in DSAIN-AMP2OUT configuration in frequency ranging between 450MHz and 650MHz and a centre frequency of 500MHz and wish to get 23dbm output across these frequencies for a 50 ohm load. I want to implement…

  • Question on ADL5243


    I am using ADL5243 for amplification. Now I need to amplify the signal which frequency is 1.2GHz, how can I choose Amplifier 2 matching components values? The datasheet don't have the correlate frequency matching components values

    Best Regard

  • ADL5243  USB coding question

    I bought the ADL5243 ADI assessment board, but when I tested the board ,I encountered problems. The board of digital attenuator (DSA) attenuation coefficient does not change when adjusting  software, I want to ask my USB programming…
  • Problem with the ADL5243 VGA


    We bought an evaluation board ADL5243 EVAL from Analog. We want to use it as the AMP1-DSA-AMP2 mode. We used two cables to connect amp1out with DSA in, DSAout with amp2in respectively, then we measured the gain of the VGA with a VNA. We found that the…

  • ADL5243 broad band matching AMP2


    is ist possible to match the internal Amplifier AMP2 from the ADL5243 over a wider bandwith than described in the datasheet. I would need to cover 950 MHz to 2150 MHz.

    Thank you.


  • ADL5240 / ADL5243 default attenuator setting

    I would like to know what the default attenuator setting is - on power up - for these variable gain amplifiers.

    I intend to use the devices in serial mode (SEL connected to GND.)
