What ASB does
ASB Inc. is a privately held South Korean RF semiconductor company, headquartered at 44-14 Techno 10-ro, Yuseong-gu, Daejeon, specializing in the design and manufacture of monolithic microwave integrated circuit (MMIC) amplifiers. The firm was founded in 1998 and operates with 11-50 employees out of a single site in Daejeon's Daedeok Innopolis high-tech cluster, where it conducts RF research and development. ASB's portfolio is organized into three application families — telecommunication amplifiers (LNAs, gain blocks, IF amplifiers, medium- and high-power amplifiers), broadcasting products (CATV, MoCA/SMATV/ONU, optical TIAs, GNSS amplifiers, DMB/DVB/CMMB), and microwave high-power amplifiers (S, C, X, Ku, Ka, and wideband) — supported by adjacent digital attenuators and SPDT switches.
The company's technical foundations are GaAs E-pHEMT for low-noise and wideband applications and GaN HEMT for high-power and microwave applications. Representative catalog specs include 20+ dB gain with 0.9-1.5 dB noise figure across 0.05-3.5 GHz in the AHL-series LNAs (MTTF > 100 years), and up to 43 dBm saturated output power in the AGN-series GaN HPAs covering 4.4-16.5 GHz. ASB positions these parts for 5G/wideband, WiMAX/LTE, WCDMA, GPS/GLONASS/Galileo, CATV, microwave backhaul, and military/defense radar and electronic warfare, with a website-hosted cross-reference tool that maps ASB equivalents to competitors such as Qorvo, Skyworks, MACOM, Analog Devices, Infineon, and Broadcom.
Commercially, ASB runs a direct-sales hardware model: enterprise customers in telecom, broadcasting, defense, and microwave integration request datasheets and engage sales by phone (+82-42-528-7220) or email ([email protected]). Pricing is not publicly disclosed. The firm has no disclosed funding events, no investor relations presence, no named parent company, no M&A activity, and no senior leadership disclosures in the public materials reviewed, making the ownership and revenue scale a matter of inference only.
