CSA121X PASSIVE WIDEBAND SPLITTER COMBINERS
• DC-coupled for use with antenna
booster/ active antennas.
• Handles up to 1.5 Amps without
saturation for high power IP3
booster driving (i.e. Wisycom BAW)
• Supplied with 230/110 Vac power
supply with locking connector
CSA121A
• Works with input power up to 2W
• DC pass-through for antenna
booster powering
CSA121B
• Works with high input power – up to
3W
• Becomes a smart combiner when
used with Wisycom MTK952N
(2WO) Transmitter
• Recovers combiner loss as
MTK952N increases output power
as needed
Note: the CSA121T does not have booster
pass-through capabilities

CSA121X PASSIVE WIDEBAND SPLITTER COMBINERS
Example: CSA121B in combiner conguration with high power transmitters
Example: CSA121A in combiner conguration with high-current boosters
Example: CSA121B in splitter conguration with DC pass through
Example: CSA121T in combiner conguration with high power transmitters
LBN2MTK952 CSA121B
LFAMRK980 CSA121B
LBN2MTK952N CSA121T
LFAMRK980 CSA121B
Connecting CSA121T, MTK952N automatically recovers the combiner loss increasing the output power of the transmitter.
