X3DC08E2S Anaren

Model X3DC08E2S Rev F Doherty Combiner b Description The X3DC08E2S is a low profile, high performance Doherty Combiner in a new easy to use, manufacturing friendly surface mount package. The X3DC08E2S is designed particularly for Doherty Amplifier applications, where tightly controlled phase and amplitude imbalance as well as low insertion loss are required for maximum and low power condition. It can be used in high power applications up to 200 watts. Parts have been subjected to rigorous qualification testing and they are manufactured using materials with coefficients of thermal expansion (CTE) compatible with common substrates such as FR4, G-10, RF-35, RO4350 and polyimide. Produced with 6 of 6 RoHS compliant tin immersion finish Electrical Specifications ** Features: Phase Return Insertion Amplitude Frequency Imbalance 862 - 894 MHz 1 1 1 Loss Loss Imbalance 1 High Power MHz dB Min dB Max dB Max Degrees Low Amp Imbalance Very Low Loss 862 894 20 0.15 0.12 90 3.0 Production Friendly Return Loss Insertion Port Operating Tape and Reel Power 2 2 3 Loss Extension Temp.

The length of the short line is specified as electrical length at center frequency and noted as port extension in this datasheet. The designer should take this length into the consideration to optimize the offset line length.
