Product Description
The TQ1303 through TQ1308 are a family of passive power splitters. These devices are used
to split one input power into two output powers, with min imal degradation. The input and
outputs are matched to 50 ohms and by keeping the100 ohm resistor off-chip it allows for high
power capacity.
