Application Circuit Required

Hi Abdul,

                I do not have an application circuit for the requested frequency range. I will need approximately 3 weeks to develop this circuit.

Regards,

Jim B

Thank you so much for you reply.

Dear can you please develop the application circuit and recommended component list for requested frequency range. If you can develop it as soon as possible it will be very effective.

Looking for your response.

Best Regards:)

- Is this input or output RL?

- Do you have room to lower specs, some trade off, for example Gain P1dB?

Regards

Ivan

This is output return loss.

Input return loss is 12db.

Dear these specs are the same as you given in the datasheet for other bands.

P1db shoulb be 25 db.

Gain can be 1,2 db lower as i mentioned above.

Thanks:)

Hi Abdul,

Can you tell us about  more details about opportunity? What is company name doing this design?

Reason I am asking is because we might be able to find other part fitting your design target.

Thanks

Ivan 

Our company name is aksa-sds. Aksa-sds is a design house providing engineering solution.

Hi Abdul,

               I've been working the ADL5320 matching for 950 MHz - to 1250 MHz. Based on available load pull data the achievable gain in this frequency rang is about 16 to 17 dB? Before I go further and build a physical board will this amount of gain be adequate for your requirements?

Regards,

Jim

Dear thank you so much for your efforts.I think if you get  17dB gain it will be okay.Kindly proceed for further procedure.

Hello dear are working on the application circuit ?

Hi Abdul,

                I have a circuit designed for the ADL5320. I just received eval boards so  I can implement the designed circuit and verify the performance.

Okay dear thanks for your response.After verification share the results with me.

Best regards:)

Hi Abdul,

                    Attached are the results and the matching circuit. Gain is 16 dB. There is a trade off between IP3, gain and P1dB. I chose to maximize gain & P1dB. The matching components and location of components on thPDFe EVB are in the document also.

Hi Jim, 

Hi Jim, 

Hi Jim , Thank you so much for your prompt response and helping i am really impressed. I just added the ADL5320 device to my order list. Your efforts and results are amazing. Dear just one more thing i want to know which material sheet and thickness you used for eval board. 

Dear i also need you help for HMC1099LPSDE GAn amplifier IC. Can i use it at maximum 1250Mhz  frequency because according to datasheet its frequency range up to 1.1GHz. However i did check the graphs of this amplifier and it looks like it will work fine at my frequency range which is upto 1250MHz frequency.  Also can you please recommend me a biasing circuit for  HMC1099LPSDE. It will be very helpful. You have been so helpful until now so i wanted to know your opinion on this too.Looking for your response.

Best Regards:)

Hi Abdul,

- Since ADL5320 is good enough for you, does this mean you do not need HMC789 tuning?

- when you say biasing circuit for HMC1099LPSDE, do you mean matching circuit or biasing?

if you mean biasing, that can be seen at page 14 in datahsheets.

Keep in mind that this is last time buy part, but you can use HMC1099PM5E instead.

Regards

Ivan 

Sorry dear the part number was HMC1099LP5DE GAN amplifier.Actually i was saying about biasing circuit gate supply and drain supply voltages providing circuit.

Also i just see page 14 on datasheet matching circuit is provided. But i am talking about biasing circuit.  Looking for your response.

Dear if you can provide me HMC789 application circuit i also add this device to my order list.Again thank you so much for your cooperation.

Dear just looking for your response. Dear I also need application circuit of HMC1099LP5DE for 950-1250MHz frequency band. If you can help me it will be very thank full .                                                      Best regards:)
