Product Description
A2CD930M941M70AB is a high-performance cavity duplexer designed for 930-931MHz and 940-941MHz dual frequency bands and is widely used in communication base stations, radio transmission and other radio frequency systems. Its superior performance of low insertion loss design (≤2.5dB) and high return loss (≥20dB) ensures stable signal transmission, and has excellent signal isolation capability (≥70dB @ Fo+10MHz), significantly reducing interference.
The duplexer supports power input up to 50W and operates in a wide operating temperature range of -30°C to +70°C. The product adopts a compact design (108mm x 50mm x 31mm), silver-coated housing, and is equipped with an SMB-Male interface to ensure installation flexibility and durability. It also complies with RoHS standards and supports the concept of green environmental protection.
Customization service: According to customer needs, we provide customized options for frequency range, interface type and other parameters to meet diverse application needs.
Quality Assurance: The product enjoys a three-year warranty period, providing customers with long-term reliable performance guarantee.
