Product Overview
The HS Series Bandpass Filter (BPF) is a high-performance microwave filter product independently developed by Shenzhen Huashi Digital Technology Co., Ltd. It is specifically designed for satellite communications, broadcast television, meteorological reception, and other application scenarios. The HS series effectively mitigates 5G base station signal interference, ensuring stable operation of receiving systems.
The product covers multiple frequency bands including P-band, L-band, C-band, X-band, Ku-band, Ka-band, Q-band, V-band, and W-band. Utilizing premium silver/aluminum/copper cavity structures, the HS series delivers excellent performance characterized by low insertion loss, high out-of-band rejection, low VSWR, and high power capacity.
■ Key Features
- Ultra-low insertion loss design for high-efficiency signal transmission
- Superior out-of-band rejection performance, effectively resisting 5G interference
- Standard waveguide flange interfaces for quick and easy installation
- Aluminum alloy / copper alloy cavity construction — robust and thermally efficient
- Black paint surface treatment — corrosion-resistant and anti-aging
- Wide frequency coverage with full support for custom specificationsWaveguide Flange TypesAll HS series filters employ standard waveguide flange interfaces per IEC 60154-2, ensuring compatibility with industry-standard equipment.
