The QAM Modulator and Demodulator IP cores, provided by UTS are FPGA proven high data rate QAM IP solution. These IP cores can use for modulating data signals onto a carrier used for radio communications. QAM is a signal in which two carriers shifted in phase by 90 degrees are modulated and the resultant output consists of both amplitude and phase variations. These IP cores can meet High speed data rate applications on FPGA’s

UTS offers IPs under flexible licensing models, to meet requirements of different category of users. The low cost reference designs are distinguished from IPs with less (or no) document (end user/project) execution for licensing.  Read more from IP main page.

UTS offers transparent and pre-committed pricing model for a minimum period of five years from the date of order  to migrate from per product based licensing to unlimited licensing or source code licensing models. With this the system developers have clear estimate of the cost in the volume production, right at the time of prototype development.

IP based on user specification

UTS also takes up development of complex algorithms based on the end performance specifications as per user requirements. In certain fields UTS also takes up this development on No cost - No commitment (NCNC) model. Based on the project category the UTS share on IP rights can be worked out for mutual benefit.
