X3DC21P1S
Rev F
Doherty Combiner
Description:
The X3DC21P1S is a low profile, high performance Doherty
Combiner in a new easy to use, manufacturing friendly surface
mount package. The X3DC21P1S 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 50 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 TTM Technologies 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 7° at 2150MHz. Details in page 2.
[4] 70W output from each PA for short duration @ max power condition. Details in page 5.
