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…
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…
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…
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
I would like to ask some questions on the ADL5243. Earliest replies would be appreciated.
Please refer to the ADL5243 datasheet , Rev. B.
Q1: NC pins
In Table 3. It is said NC pins should not be connected , but they are connected to GND in Figure…
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…
To EZ staff,
I posted some questions on the ADL5243 and HMC1118 about ten days ago, but still have not
rereived any answer from anybody.
Any response would be appreciated.
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.
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.)
