Doherty Combiner
The X3DC07E2S is a low profile, high performance Doherty Combiner
in a new easy to use, manufacturing friendly surface mount package.
The X3DC07E2S 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

**Specification based on performance of unit properly installed on Anaren Test Board
[1] At maximum power condition, Doherty combiner functions as an equal-split power combiner.
[2] At low power condition, Doherty combiner functions as a 100Ω to 50Ω impedance transformer.
[3] There are short 50 ohm lines associated with input ports of 0° at 748MHz. Details in page 2.
