DC Pass Bi-Directional Coupler 5022 Up to 100W 800 to 2500 MHz

Category: Electronics, Minicircuits, RF Microwave Devices

Overview

The datasheet presents detailed information regarding the Mini-Circuits ZABDC20-252H series Bi-Directional Couplers. These devices are designed to operate over a broad frequency range of 800 to 2500 MHz and can handle high power levels up to 100W. The datasheet outlines the maximum ratings for operating and storage temperatures and DC current, as well as the electrical specifications relevant to the performance of the bi-directional couplers.

Maximum Ratings

The operating temperature range is from -55°C to 100°C, and the same range applies to storage temperatures. The DC current handling capability is rated at 2A. Users are cautioned that these limits should not be exceeded to avoid permanent damage.

Key Features

Highlighted features of the bi-directional couplers include:

– Excellent mainline loss with a typical value of 0.17 dB.

– High directivity, typically rated at 28 dB.

– The ability to handle high power up to 100W.

– Rugged shielded casing.

– The capacity for 2.0A of DC current to pass through from input to output at 50W RF input power.

Applications

The bi-directional couplers are suited for various applications such as PCS/DCS/UMTS power leveling and monitoring and VSWR measurement.

Model Variants

Models vary by the type of connectors used: SMA (ZABDC20-252H-S+) and N-Type (ZABDC20-252H-N+). The “+Suffix” indicates RoHS compliance.
