Duplexer / Diplexer — 223 MHz to 16.2 GHz

Description

Duplexer / Diplexer — 223 MHz to 16.2 GHz

Product Overview

HS Series Duplexers are high-performance passive RF devices independently developed by Shenzhen Huashi Digital Technology Co., Ltd. They are designed for base stations, satellite communications, repeaters, broadcasting, and military communication systems, enabling simultaneous transmission and reception on shared antennas while maintaining high isolation between Tx and Rx paths.

Key Features

• High isolation up to 95 dB, ensuring clean Tx/Rx separation
• Low insertion loss design for maximum signal efficiency
• Wide frequency coverage: 223 MHz to 16.2 GHz
• Standard N-K / SMA-K / Waveguide interfaces for easy integration
• Rugged aluminium cavity construction, excellent heat dissipation
• Surface black paint treatment, corrosion and aging resistant
• Custom frequency bands and isolation levels available on request
