Hi,can you help to support the gerber data or the pcb layout of EV-DEMORAD24G,our customer wish get that  for reference in their own 24G radar circuits.Thanks.

Hi, I am using HMC920 to bias HMC637A. Queries: 1)In HM920 what is the relation  between VDD and V(LDOCC)? 2)In order to bias HMC637A I need V(LDOCC)= 12.20. To get  V(LDOCC)= 12.20, my VDD has to be greater than 12.22(Correct me if I am wrong) 3)If above assumption is wrong can I get V(LDOCC)= 12.20 with VDD=5V 4)If my assumption in query 2… (Show more)

Dear Sirs, since four years we used the ADRF6602 as a down-converter. LO freq. = 1605,425MHz. We never changed the hardware (PCB) and also the software was never changed. The converter worked fine the hole time. Now - arround four years later a problem appears: arround 40% of the used chips can't lock the PLL after init the register. Here are… (Show more)

Regarding the ADF4156 datasheet, according to table 1, the RF IN (for single pin or for both pins combined??) require/s power between -10dBm to 0dBm. According to figure 5, it seems the RF power required is below -15dBm all over the usable range (I probably did not understand the meaning of "RF sensitivity" there).   What is my understanding… (Show more)

Hi everyone,   I would like to design a circuit with 2 x HMC797APM5E with 2 x bias controllers (the right one seems to be the HMC980LP4E).   This is my needs : - Amplify DC to over 20GHz signal - Input : 0 to 350mV and need an output 0 to 5Vmin (so P1dB min +24dBm) - Would like the cleanest signal as possible, stay in linearity part.   No… (Show more)

Will Active bias controller(HMC920) support  HMC994 and HMC8410? If yes why it is not listed out in the datasheet of HMC920? If no Suggest me Active bias controller for HMC994 and HMC8410?

Hello,   I have two questions about this IC.   - Does anybody know the detailed repartition of the DC power consumption of the ADRF6518. I mean on each pin : VPSD, VPI, VPS?   - Is the register content lost if ENBL pin is drive low ? (the goal is to put the IC in shutdown after having programming it, and wake it up later)   Thanks.

The datasheet describes: "avoid RFx pins left open circuit". Is this also valid for RFC?

Is there a LabVIEW source code for the EV-RADAR-MMIC software or library that one can use to create automated testing routines? I have the EV-RADAR-MMIC connected through SDP-B and would like to be able to write to the registers using LabVIEW just as you would do it in the software.   Any advice is appreciated thanks.

Hello, I am using HMC703 for a design.After powering up the board,I use Hittite USB Interface to make the HMC703 locked first.Then i pull out the SCK,SDI and SEN and connect them to FPGA board.Then I can control the HMC703 by FPGA board,such as changing the frenquency and turning to sweep mode.However,when I use FPGA board to control the HMC703… (Show more)
