Product Description
A2CD901M931M70AB is a high-performance cavity duplexer designed for 901-902MHz and 930-931MHz dual frequency bands and is widely used in communication base stations, radio transmission and other radio frequency systems. The product has superior performance of low insertion loss (≤2.5dB) and high return loss (≥20dB), ensuring stable signal transmission, while its excellent signal isolation capability (≥70dB) significantly reduces interference.
It supports power input up to 50W, adapts to a wide temperature operating environment from -30°C to +70°C, and meets the application needs of a variety of harsh environments. The product has a compact structure (108mm x 50mm x 31mm), uses SMB-Male interface, and has a silver-coated housing, which is both durable and beautiful, and complies with RoHS environmental standards.
Customization service: According to customer needs, we provide customized options for frequency range, interface type and other parameters to meet the needs of different application scenarios.
Quality Assurance: The product enjoys a three-year warranty period, providing customers with long-term reliable performance guarantee.
