SP-2G1+

Mini Circuits SP 2G1 · Signal Buffers, Repeaters, Splitters · SOT-23-6

SP-2G1+ from Mini Circuits SP 2G1, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	PORT 1	passive	RF Port 1. One of the two 50Ω output ports when used as a splitter, or one of the two input ports when used as a combiner. Bandwidth 1200-2000 MHz.
2	GROUND	power_in	RF/DC ground return. Must connect to the PCB ground plane per the suggested PCB layout (PL-232).
3	PORT 2	passive	RF Port 2. One of the two 50Ω output ports when used as a splitter, or one of the two input ports when used as a combiner. Bandwidth 1200-2000 MHz.
4	GROUND	power_in	RF/DC ground return. Must connect to the PCB ground plane per the suggested PCB layout (PL-232).
5	SUM PORT	passive	Summed (S) RF port. Common port that feeds both Port 1 and Port 2 as a splitter, or receives the combined signal as a combiner. 50Ω, 1200-2000 MHz.
6	GROUND	power_in	RF/DC ground return. Must connect to the PCB ground plane per the suggested PCB layout (PL-232).
