3W525

3W525 Surface Mount Balun VER9/22/00 Features: 1.8 – 2.5 GHz 180° Transformer 50 Ohm to 25 Ohm Broad Band Low Insertion Loss High Power Even Order Harmonic Suppression Input to Output DC Isolation Surface Mountable Tape & Reel Convenient Package Description: The 3W525 is a low profile balanced to unbalanced transformer designed for push-pull amplifiers in an easy to use surface mount package for PCS, DCS, . These compact Xinger® surface mount baluns are ideal for high volume manufacturing and are more reliable and repeatable than traditional baluns. The 3W525 has an unbalanced port impedance of 50Ω and balanced port impedances of 25Ω to ground with a 50Ω balance between outputs. This eases the matching of the push-pull amplifier’s power transistors, which have low impedance levels. The output ports have equal amplitude (-3dB) with 180 degree phase differential. The Xinger® balun is a res ult of years of research and development culminating with a solution so unique, a patent is pending on the design approach. The 3W525 is available on tape and reel for pick and place high volume manufacturing. www.DataSheet4U.com 3W525 MECHANICAL OUTLINE: ELECTRICAL SPECIFICATIONS: 3W525 - Surface Mount Balun Parameter Operating Frequency Unbalanced Port Impedance Balanced Port Impedance (2ó3) Unbalanced Port Return Loss Insertion Loss (max) Output Amplitude Balance (p-p) Phase Balance Power Rating (max) ΘJC Specification 1.8-2.5 GHz 50Ω 50Ω (25Ω to Ground) -15dB ...
