What is the expected growth rate for the broad markets business in the March quarter 
y what is the direction of content that you are seeing in these 5G smartphones? And I think you mentioned integration. Is it kind of a winner-take-all in some of these initial wins or are you still kind of maintaining your share in the specific components that you have expertise in?
Liam K. Griffin -- President and Chief Executive Officer
Sure. Well, the way we're seeing it right now we believe we're absolutely gaining share in 5G and the rollout of these new highly complex phones are exactly what we want to see. We're continuing to gain share with our Sky5 platform. We're doing the very difficult things that we've been talking about in prior calls, really crafting and creating these wonderful devices that are going into 5G-enabled phones. We're seeing that across a number of customers, great position in China with a number of leading players, position at Samsung and then also with some of the larger players in the US that haven't even launched their 5G phone yet. So there's a lot of positive momentum there and we feel very -- very upbeat about where we're going in the second half.

Got it. And my follow-up is kind of a strategic question. So you have been developing your internal ball capability for some time, but one of your competitors put up their RF assets for sale. I'm curious if those assets get sold to a potential competitor or a customer, what's the impact or are those assets something that you might be interested in taking a look at? Just how should we think about kind of the impact of this potential consolidation on Skyworks?
Liam K. Griffin -- President and Chief Executive Officer
Sure, sure. Appreciate the question. Well, we really can't get into any specifics around M&A. We're well aware of the opportunity that you just suggested, but at the same time we are really happy with what we're doing in our organic business and we see a tremendous opportunity there with 5G now just starting and the momentum in our demand really accelerating. So we feel good about it, but at the same time we have to look at M&A opportunities and I'm pleased to say that we have the powder and the cash flow to do deals when deals are necessary. But at this point, we really just can't comment on anything specifically.

And your next question comes from the line of Timothy Arcuri from UBS. Your line is open.
Timothy Arcuri -- UBS -- Analyst
Thanks so much. Kris, can you give us the splits for both businesses for December and how you think about it for the guidance for March?
Kris Sennesael -- Senior Vice President and Chief Financial Officer
Yeah. So our broad markets business in the December quarter was approximately 27% of total revenue. That is in line with what we saw last year. Keep in mind that December quarter is typically a very strong mobile quarter with obviously a lot of business with our large customer and then the ramp of 5G phones. So mobile was 73% of total revenue.
Looking forward into the March quarter, that is where we see a little bit of a flip, right. This is typically a stronger broad markets quarter. We do expect some mid-single digit sequential growth in our broad markets business and we will see some mid single to -- yeah, mid single year-over-year growth in broad markets in the March quarter and then of course even further stronger growth in the second half of 2020.
Timothy Arcuri -- UBS -- Analyst
Great, thanks for that. And can you just talk about Huawei and how it ended up playing out? I think you expected about $10 million. And my guess is that it was maybe a little bit better than that. But how did it play out and sort of how do you think -- not just about them as a customer, but how do you think about how the export restrictions might change and how that is impacting what that customer and what's your other Chinese customers are pulling? How hard they might be pulling? Are they perhaps double ordering? Thanks.
Liam K. Griffin -- President and Chief Executive Officer
Sure. Well, obviously, it's an evolving situation and we have a really dynamic b
