Product Overview

CMD175P4 is a 5-bit digital phase shifter based on GaAs MMIC technology, housed in a lead-free, RoHS-compliant 4x4 mm QFN package. It operates in the 2-4 GHz frequency range, providing 0-360° monotonic phase coverage with a minimum step (LSB) of 11.25°. Controlled by single-bit negative logic (0 or -3 V), the device features a 50Ω matched design, eliminating the need for external DC blocks and RF port matching components, thus delivering precise phase adjustment for RF systems.

Key Features

• Low Phase Error: Typical phase error of ±5°, ensuring high precision in phase adjustment, suitable for RF applications with strict phase accuracy requirements.
• Low Insertion Loss: Typical insertion loss of 7 dB, reducing energy loss during signal transmission and improving overall system efficiency.
• Full Phase Coverage: Achieves 360° complete phase adjustment with a minimum step of 11.25°, flexibly meeting various phase adjustment needs.
• Simplified Design: 50Ω matched design eliminates the need for external DC blocks and RF matching components, simplifying circuit design and shortening development cycles.
• Eco-Friendly and Reliable Package: Adopts a 4x4 mm lead-free QFN package, compliant with RoHS standards, suitable for high-density PCB layouts with good heat dissipation performance.

Technical Specifications

Typical Applications
