DB HiTek Expands RF Front-End Business With RF SOI/HRS Process


SEOUL, South Korea–(Business enterprise WIRE)–DB HiTek had declared to expand the RF front-conclusion business by securing RF SOI (Silicon-on-Insulator) and RF HRS (Higher Resistivity Substrate) course of action centered on 130nm/110nm know-how.

RF entrance-close is a obligatory solution for wireless conversation which is responsible for transmit (Tx) and receive (Rx) involving IT products, and applied diversely to the communication spots which include smartphones and IoT, and so forth. Generally, just about every component this kind of as an antenna tuner, a change, a reduced sounds amplifier (LNA), and a ability amplifier (PA) is assembled on the item.

The importance of RF entrance-close is progressively increasing whilst the desire on substantial-top quality communications with significant frequency, superior-sensibility as the wi-fi interaction engineering develops to 5G. Accordingly, the RF entrance-end current market is forecast to have a rapid advancement from USD12.4 billion in 2019 to USD21.7 billion in 2025.

Among a lot of elements of the RF entrance-conclusion, DB HiTek particularly focuses on the change and LNA (Minimal Sound Amplifier). The swap is dependable to convert on/off though transmitting/receiving the frequency, and LNA is the core product or service for superior-pace interaction like 5G by transferring the extra accurate sign as amplifying the frequency.

DB HiTek experienced greatly enhanced the options by including SOI and HRS wafers which blocks or reduce the leakage latest to the earlier RF bulk process.

Especially, in circumstance of the RF SOI course of action primarily based on 130nm technologies, DB HiTek has the world’s best-course options for switch FOM (Figure of Advantage) of 84fs, BV (Breakdown Voltage) of 4.4V. LNA is readily available to assist up to 120GHz Slice-off frequency (Ft), and will be attainable to aid up to far more than 150Ghz inside the to start with fifty percent of 2022.

RF HRS (Large Resistivity Substrate, >1Kohm) course of action primarily based on 110nm engineering has great price tag competitiveness. The swap FOM is 164fs and BV is 4.6V, and the LNA can assist 100GHz Minimize-off frequency operate. The LNA products of 150GHz or higher are below enhancement for aid inside the initially fifty percent of 2022.

DB HiTek is positively established out to consumer support to allow fabless consumers to enter the RF front-conclusion market place at the right time, particularly, it quarterly operates MPW to preserve sources of client corporations.
