SEOUL, South Korea–(BUSINESS WIRE)–DB HiTek had announced to expand the RF front-end business by securing RF SOI (Silicon-on-Insulator) and RF HRS (High Resistivity Substrate) process based on 130nm/110nm technology.

is a mandatory product for wireless communication that transmits (Tx), and receives (Rx) between IT device. It can be used in a variety of communication areas, including smartphones, IoT, and IoT. The product usually includes every component, such as an antenna tuner and switch, a low-noise amplifier (LNA) and a power amplifier.

As 5G wireless communication technology advances, the importance of RF front end is increasing. Accordingly, the RF front-end market is forecast to have a rapid growth from USD12.4 billion in 2019 to USD21.7 billion in 2025.

DB HiTek focuses on LNA (Low Noise amplifier) and the switch. The switch is responsible to turn on/off while transmitting/receiving the frequency, and LNA is the core product for high-speed communication like 5G by transferring the more accurate signal as amplifying the frequency.

DB HiTek has significantly improved these features by adding SOI wafers and HRS wafers that block or minimize leakage current to the RF bulk process.

Especially, in case of the RF SOI process based on 130nm technology, DB HiTek has the world’s top-class features for switch FOM (Figure of Merit) of 84fs, BV (Breakdown Voltage) of 4.4V. LNA is available to support up to 120GHz Cut-off frequency (Ft), and will be possible to support up to more than 150Ghz within the first half of 2022.

RF HRS (High Resistivity Substrate, >1Kohm) process based on 110nm technology has excellent price competitiveness. The switch FOM is 164fs and BV is 4.6V, and the LNA can support 100GHz Cut-off frequency function. For support in the first half 2022., LNA products with 150GHz and higher are currently under development.

DB HiTek is committed to customer support in order to enable fabless customers to access the RF front-end markets at the right time. It also quarterly operates MPW to reduce customer company’s resources.
