* Qualcomm to pay T$390 mln for first installment of fine
* Total fine of T$23.4 bln to be paid in 60 installments
* Chipmaker has been penalised in other jurisdictions (Adds details, context in paragraphs 1-3,6)
TAIPEI, Jan 30 (Reuters) - Qualcomm Inc will pay T$390 million ($13.35 million), its first installment of a fine for anti-trust violations in Taiwan, the Taiwan Fair Trade Commission said on Tuesday, as the U.S. chipmaker grapples with issues around its business model.
The first payment is part of 60 installments that Qualcomm will have to fork out for the fine totalling T$23.4 billion the commission slapped on the chipmaker for the violations, the regulator told a news conference.
As part of the agreement, the chipmaker will make monthly payments over the next five years to pay off the fine, the commission said.
Earlier, the commission said Qualcomm had a monopoly over the chip market for several so-called modem technologies, which provide wireless data connectivity for mobile phones, and refused to licence its technology to other industry players.
Qualcomm's fine is the latest in a years-long streak of regulatory setbacks to its business model that comes as it also fights U.S. regulators and iPhone maker Apple Inc in court over many of the same legal issues.
In December 2016, South Korean regulators fined Qualcomm $854 million for violating its competition laws, a ruling that followed a $975 million fine from Chinese regulators in 2015.
