| > RF CMOS - Pioneers from the early days |
|
Having pioneered CMOS RF technology during the 90’s and successfully integrated CMOS RF systems in GPS, DECT, sub 1GHz ISM, and Bluetooth systems and sub-systems we continue to develop high performance, state-of-the-art, fully integrated CMOS RF solutions.
Over the last years we have gained extensive experience in highly linear OFDM based systems for multiband and multimode wireless networks based upon our Software Defined Radio technology. Our deep understanding and experience enables us to design radio architectures that are ideally suited to each customer’s application, taking into account the optimum combination of lower component count, lower power consumption, lower power supply levels, lower physical dimensions and lower costs.
AnSem’s Key Design Expertise includes:
- Integration of systems such as sub 1GHz ISM, GPS, DECT, Bluetooth and WiMAX
- Advanced architecture techniques such as:
- Low-IF reception
- Digital demodulation from low-IF
- Direct digital modulation of PLLs for transmitters
- Fractional-N synthesizers
- Reconfigurable filter design
- Wideband, highly linear LNA & PPA topologies
- Low loss RF circuit design and layout for highest Q factor
- Wireless chip developments for applications between 200MHz and 4GHz
- Power supply levels down to 0.9V
AnSem’s technology experience ranges from 0.8µm BiCMOS down to 40nm CMOS
