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 would suggest the ADL5243 RF VGA as a possible solution for the Amp. P1 dB is 26 dBm @ 2140 MHz.
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…
Moved this question here in RF and Microwave community. RReeder would help you about ADL5243 questions.
A circuit to match AMP2 on the ADL5243 from 950-2150MHz will be very difficult to implement. A 300-400MHz match is the best we have been able to achieve with surface mount components. I would suggest experimenting with the s-parameter model file provided…
