Frequently Asked Questions

What is the advantage of a positive bias supply voltage and where can I see all your positive bias devices?
 

The requirement for only a positive bias supply for a GaAs MMIC amplifier greatly simplifies the design implementation. No negative supply nor complicated power up sequence circuitry is needed. Size weight and power (SWaP) are saved as a result. The great majority of Custom MMIC’s amplifier products require only a positive bias supply, often only a single supply with self-biasing. Please visit our search by band page and filter on positive bias to a see a complete list of positive bias solutions: www.custommmic.com/search-by-band/ 

Does Custom MMIC space qualify any of their products? To what standards?
 

Custom MMIC has space heritage and has qualified several of its products per MIL-PRF-38534 Class K and MIL-PRF-38535 Class S. Most of the Custom MMIC product portfolio can be screened for use in space. To learn more visit custommmic.com/space-qualification

What foundries does Custom MMIC use?
 

Custom MMIC has strong and long standing relationships with essentially all the GaAs foundries in the world. We select the foundry based on the performance and price goals for the particular product.

Where can I find S parameter data on a particular product?
 

S-Parameter data for each Custom MMIC product can be found on the product page on each model's overview page by clicking the model number in the left column of any table. One time registration is required.

Do you provide evaluation boards for your packaged MMICs?
 

Yes. We have connectorized, fully assembled evaluation boards for all of our packaged MMICs. Please fill out our Request a Quote form and we will be happy to assist you.

I would like to download your full product list – How can I do that?
 

You can download our full selection guide above under company information above.

I see a lot of standard MMIC products on your web site – do you still do custom design?
 

We are regularly introducing new standard products but Custom MMIC still undertakes custom design for GaAs and GaN requirements. Please visit http://www.custommmic.com/process/ for a description of our custom development process methodology, or fill out our Request a Quote form to supply your application requirements.

Do you offer replacement parts for MMICs obsoleted or deemed end-of-life by other suppliers, such as Broadcom / Avago and MACOM?
 

Yes. While not always a direct replacement, our catalog is full of devices from stock that often require require little to no redesign. We can also re-engineer or reverse engineer a design and fab your devices. To get started, visit our support page and submit a request to our technical team with the details. To learn more about our Avago replacement options read our blog.

What should be done with no connect (N/C) pins on packaged parts?
 

Custom MMIC datasheets generally indicate N/C pins can be either left open, or grounded. Either approach will not affect the performance of the part. Most customers choose to ground the N/C pins.

Are all of your pHEMT MMICs space qualified?
 

In general, we rarely get radiation questions about GaAs products because for most applications the inherent hardness of GaAs devices will satisfy the mission requirements. While all parts have not been previously for space, they are part of a family that is done on the same GaAs pHEMT process of which we have qualified multiple parts to class K for space applications.
