Low Frequency 50 ohm Combiners-Splitters

20 kHz to 4.0 Mhz Combiner-Splitter

This combiner has three ports that can be used as a 50 ohm combiner or splitter from 20 kHz to 4.0 MHz.

Combiner
Ports 1 and 2 are the two signal sources that are combined at port 3. Ports 1 and 2 need to connect to a 50 ohm source. Likewise port 3 needs to see a 50 ohm load.

Splitter
Port 3 is the 50 ohm signal source. Ports 1 and 2 are the split signal that must see a 50 ohm load.

Insertion Loss: 6 dB

Maximum Signal Transfer: 5 watts

Dimensions: 5.5 in(14 cm) x 2.5 in(6cm) x 2.25 in(6.7cm)

Connectors: BNC (standard), N, SMA (gold female)

Port to Port (1 and 2) Isolation

A signal source enters port 1 or 2 as the reference level,
and the other port is terminated in 50 ohms. The residual
level is then measured in relation to the signal source.
