What is the expected revenue growth rate for the Infrastructure Division (IDP) in the back half of the year
ure, Bill. This is Eric. So we are seeing an acceleration, really, in 5G activity throughout China, certainly not just Huawei, but all of our leading handset customers in China. A lot of excitement about the rollout and it's definitely accelerating, as Bob mentioned in his opening comments, both in terms of licenses and infrastructure rollout.
But in terms of all the exciting new devices that are coming out. So we are seeing broad-based activity across all customers and across our entire product family. Certainly, antenna management, advanced power management, and highly integrated modules covering low, mid, high and ultrahigh band frequencies. So it's a very active design cycle.
Now we do see multiple 5G basebands ramping. And, of course, Qualcomm is doing well there. We do see large opportunities for content shipping on all the base bands including Qualcomm.

OK.Thanks for that. And I guess based -- this is a question on IDP. We saw sequential decline here in the June quarter and you're calling for that again in September, followed by improvement in the back half. I guess all that in, how should we think about growth for IDP this year? And I guess specifically, among infrastructure versus WiFi and defense and so forth? Thank you.
Bob Bruggeworth -- President and Chief Executive Officer
So let me talk a little bit about the current quarter. We did have a strong base station quarter in the current quarter and we are well-positioned with most of the major OEMs. That strength has come because of 5G deployments, to follow-up on Eric, because we are seeing strong demand from massive MIMO products and we do see GaN continuing to take slots particularly in those massive MIMO slots. So base station did have a strong quarter.
As far as projecting out further, we have experienced several weak quarters of our IoT particularly our WiFi part of that business. We believe that still delays associated with the rollout of AX and a little bit to do with trade activities and repositioning of supply chains. We had a very strong design win quarter in that part of the business. So we are starting to see indications that we are coming out of that and that we should have a strong back half.
So we are expecting that back half. And we also have talked in the past about our defense business being a bit lumpy. But it does look like we are positioned to have a very strong back half in the defense business. On top of that, Bill, I think we are starting to see some early indications of the infrastructure business, the supply chain starting to adjust.
We are -- we do have some of our other customers that will begin ramps soon with massive MIMO products and that will start to fill in a bit. Predominantly though, the decline that we've experienced this quarter and next quarter are associated with our lack of ability to ship to Huawei.
Mark Murphy -- Chief Financial Officer
Bill, maybe just to help a bit with the profile of IDP. Clearly had a sequential decline in the June quarter. We expect another sequential decline in the September quarter. Expect the business to return to sequential growth in the December quarter.
As it relates to year over year, the business still grew in June despite the issues with Huawei. However, in the September quarter, we do expect a decline year over year for IDP and then IDP returning to growth in the back half year over year.

Thank you. We will take our next question from Raji Gill of Needham & Company.

Thanks for taking my questions. I appreciate it. I just wanted to get a sense from you in terms of are you seeing any competitive solutions for your HBT solutions and your FinFET from -- in Asian customers? We've seen some commentary out of some FE houses that are qualifying and ramping with new Asian customers. I'm just wondering if that -- if you're seeing any competition from your main products as it relates to the China trade war and any risk in China trying to in-source where possible?
