Description

Product Overview

The HS-CP series directional couplers cover a broad frequency range from 500 MHz to 40 GHz, offering various coupling values (5/10/15/20/30/40 dB), connector options (SMA/N/2.92mm), and power handling (10W–100W) to meet the demands of RF test & measurement, communication systems, radar, and electronic warfare applications.

Featuring precision RF transmission-line structures and optimized coupling designs, the series delivers low insertion loss, high directivity, and excellent VSWR across wide bandwidths — making it an ideal choice for RF signal monitoring, power splitting, and system debugging.

Key Features

• Broadband Coverage: 500 MHz – 40 GHz (model-dependent segmentation)
• Multiple Coupling Values: 5 / 10 / 15 / 20 / 30 / 40 dB
• High Directivity: Typical 20–25 dB for superior main/aux isolation
• Low Insertion Loss: As low as 0.3 dB (low-frequency models)
• Excellent VSWR: ≤1.5 : 1 across the band
• Versatile RF Interfaces: SMA-F / N-F / 2.92mm-F
• High Power Handling: Up to 100W (N-connector models)
• Rugged aluminum housing with superior thermal dissipation
• Operating temperature -40°C to +85°C for harsh environments
• Typical Applications
