BDCH-25-272+-1

STRIPLINE SURFACE MOUNT FUNCTIONAL DIAGRAM KEY FEATURES • High power handling, up to 150W APPLICATIONS • Power amplifiers • Antenna feeds • Mobile satellite communication • Digital communication applications PRODUCT OVERVIEW Mini-Circuits' BDCH-25-272+ is a high-power bi-directional coupler providing high power handling up to 150 W and mainline loss of 0.2 dB. High directivity of 19 dB provides accurate sampling from the coupled port, and 29 dB return loss provides excellent matching over full frequency range. Covering frequencies from 700 to 2700 MHz, the model supports a wide variety of applications from power amplifiers and antenna feeds to various digital communications and more. The coupler is designed into an open printed laminate (1.00" x 0.50" x 0.051") with wrap-around terminations for good solderability and easy visual inspection. 1. Tested on Evaluation Board TB-863-1+. De-embedded to the device reference plane. 2. Model is symmetrical and all ports are interchangeable, see Port Function Description/Configuration table for details and S-Parameters for actual performance. 3. Does not include theoretical loss due to coupling. Nominal theoretical loss is 0.01 dB. 4. Thermal Resistance is defined as, example (®jc= (Hot Spot Temperature on DUT - Base Plate Temperature)/Input Power) ABSOLUTE MAXIMUM RATINGS5 Operating Case Temperature6 5. Permanent damage may occur if any of these limits are exceeded. 6. Case temperature is defined as temperature on base plate.
