High-Frequency Precision for Demanding Applications
The ZSDC-107127-10S Directional Coupler is a critical RF component optimized for 10.7–12.75GHz high-frequency systems, combining 15dB minimum directivity, ultra-low insertion loss (0.7dB max), and 50W high-power capacity. Engineered with advanced microstrip technology and ceramic substrates, this coupler ensures stable performance even under extreme temperatures (-40℃ to +70℃), minimizing signal distortion for reliable operation in mission-critical scenarios.
Technical Excellence Across Multiple Dimensions
● Accurate Coupling in High-Frequency Bands
Covering 10.7–12.75GHz, this coupler supports Ku-band satellite communications (partial 12-18GHz range) and 5G millimeter-wave testing. Its ±0.7dB coupling flatness guarantees consistent signal distribution, eliminating performance fluctuations caused by frequency drift.
● Minimal Loss & Superior Isolation
With a primary insertion loss of 0.7dB (excluding 0.46dB coupling loss) and 15dB directivity, it effectively isolates forward and reflected signals, making it ideal for VSWR monitoring, power amplifier optimization, and precision RF measurements.
● Robust Industrial Design
Built with a fully shielded metal housing and SMA-Female connectors, it withstands repeated mating cycles. The ceramic substrate ensures resistance to thermal stress, corrosion, and humidity, enabling durability in harsh conditions like aerospace or military deployments.
● High-Power Compatibility
Supports 50W continuous input power (2W reflected), making it suitable for radar transmitters, satellite ground stations, and other high-power systems without performance degradation due to overheating.
