The Mounting & Bonding section of HMC-SDD112 datasheet recommends to use 5mil or 10mil thick "Alumina Substrate Thin Film" to bring the RF to and from the chip. For my specific application, I want to use a 4mil thick substrtae from Rogers Corporation…
The HMC-ALH509 can be plasma cleaned. The air bridges are part of the GaAs HEMT fabrication process. When you ask about vacuum, are you referring to picking the die with a vacuum tip? The air-bridges are fairly robust but can be damaged if not…
Program Reg0Ah = 1800h. If it is left at its default value (2005h), the VCO Auto-calibration feature is enabled and will be triggered every time a frequency is programmed. This feature is only used on HMC PLLVCO products that use the same PLL die as the…
Do you have any performance data or plots vs. temeperature for the HMC-ALH444 Die? I need to operate over an ambient temperature range from -20 to +70 and would like to know how the device will perform. Thanks.
I support the HMC1144 and can answer regarding that product, though I support neither the HMC-ALH509 nor the HMC-AUH320 and thus cannot answer for either of those products. The applications engineer(s) who support those products should soon…
The HMC-SDD112 is a part acquired from another company. The only test data provided was the scalar s-parameters. We have not performed any large signal test (P1dB and IP3) on this die part.
Based on the device size, expected P1dB and expected maximum…
I see in the datasheet for the HMC-ALH382 LNA that the bond pad width and gap are both 100 um (page 4), giving an effective pitch of 200 um. Would I be able to measure this device using 150 um GSG probes?
Yes you can use HMC981LP3E to bias HMC-ALH476. In order to change the default Vgate and Vneg threshold values you need to use external resistors. R4 and R6 resistors, at the attached circuit, change the -2.5V value to -1V for this application. Circuit…
currently we DO NOT offer the 3D models for these products.
the detailed package drawings and dimensions are included in the datasheet along with the S-parameter plots.
I will use HMC-abh209 / HMC-alh382 / HMC-sdd112 in my design,
Would you please help to provide as below?
1. S parameter
2. Input R + jX
3. Output R + jX
4. Gerber file
