3W512

Model 3W512 Rev. B 50 Description to 12.5 Balun Balanced The 3W512 is a low profile balanced to unbalanced transformer designed for pushpull amplifiers in an easy to use surface mount package for PCS, DCS, and UMTS. These compact Xinger® surface mount baluns are ideal for high volume manufacturing and are more reliable and repeatable than traditional baluns. The 3W512 has an unbalanced port impedance of 50Ω and balanced port impedances of 12.5Ω to ground with a 25Ω 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 result of years of research and development culminating with a solution so unique, a patent is pending on the design approach. The 3W512 is available on tape and reel for pick and place high volume manufacturing. www.DataSheet4U.com Features: ELECTRICAL SPECIFICATIONS*** Frequency GHz 1.8 – 2.2 GHz 180° Transformer 50 Ohm to 12.5+j5.5 Ohm Broad Band Low Insertion Loss High Power Even Order Suppression Input to Output DC Isolation Surface Mountable Tape & Reel Convenient Package Unbalanced Port Impedance Ohms Balanced Port Impedance* Ohms Return Loss dB Min Insertion Loss** dB max 1.8 – 2.2 Amplitude Balance dB max 50 Phase Balance Degrees max 12.5+j5.5 Power Handling Watts 15 ΘJC ºC / Watt 0.40 Operating Temp. ºC 0.40 180+ 5.0 150 11.3 -55 to...
