CKRF2179MM26-C4 from CDK, in a SOT-363. 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 | RF1 | bidirectional | RF port 1; active (ON) when VC1=Low, VC2=High; insertion loss ≤0.65 dB max over 0.05-3.0 GHz; max input power +33 dBm (at VC(H) 3.0-5.0 V, f ≥0.4 GHz). |
| 2 | GND | power_in | Ground reference for the pHEMT GaAs die; return path for all RF and control signals. |
| 3 | RF2 | bidirectional | RF port 2; active (ON) when VC1=High, VC2=Low; insertion loss ≤0.65 dB max over 0.05-3.0 GHz; max input power +29 dBm (at VC(H) 3.0-5.0 V, f 0.05-0.4 GHz). |
| 4 | VC2 | input | Switch control voltage 2; VC(H)=+1.8 to +5.3 V (TYP. +3.0 V), VC(L)=−0.2 to +0.2 V (TYP. 0 V); control current TYP. 1 µA, MAX. 10 µA; absolute max 6.0 V, |
| 5 | RFC | bidirectional | RF common port (single pole); routes to RF1 or RF2 depending on VC1/VC2 state; operating frequency 0.05-3.0 GHz; input return loss ≥15 dB min over full band. |
| 6 | VC1 | input | Switch control voltage 1; VC(H)=+1.8 to +5.3 V (TYP. +3.0 V), VC(L)=−0.2 to +0.2 V (TYP. 0 V); control current TYP. 1 µA, MAX. 10 µA; absolute max 6.0 V, |
