PE42820B-X from pSemi, in a QFN-32-EP(5x5). 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 GND power_in Ground connection for power supply and signal return paths.
2 RF1 bidirectional RF input/output port 1; must be at 0 VDC for operation without DC blocking capacitors; operates 30 MHz-2.7 GHz.
3 GND power_in Ground connection for power supply and signal return paths.
4 GND power_in Ground connection for power supply and signal return paths.
5 GND power_in Ground connection for power supply and signal return paths.
6 GND power_in Ground connection for power supply and signal return paths.
7 GND power_in Ground connection for power supply and signal return paths.
8 GND power_in Ground connection for power supply and signal return paths.
9 GND power_in Ground connection for power supply and signal return paths.
10 GND power_in Ground connection for power supply and signal return paths.
11 GND power_in Ground connection for power supply and signal return paths.
12 VDD power_in Positive supply voltage input; operating range 2.3-5.5V (normal mode) or 3.3-5.5V (bypass mode); nominal 3.3V.
13 V1 input Digital control logic input for path selection; high (≥1.17V) selects RFC-RF1 path, low (≤0.6V) selects RFC-RF2 path; maximum 3.6V.
14 GND power_in Ground connection for power supply and signal return paths.
15 GND power_in Ground connection for power supply and signal return paths.
16 VSS_EXT power_in External negative supply voltage input for bypass mode operation; range -3.6 to -3.2V; connect to GND to enable internal negative voltage generator.
17 GND power_in Ground connection for power supply and signal return paths.
18 GND power_in Ground connection for power supply and signal return paths.
19 GND power_in Ground connection for power supply and signal return paths.
20 GND power_in Ground connection for power supply and signal return paths.
21 GND power_in Ground connection for power supply and signal return paths.
22 GND power_in Ground connection for power supply and signal return paths.
23 RF2 bidirectional RF input/output port 2; must be at 0 VDC for operation without DC blocking capacitors; operates 30 MHz-2.7 GHz.
24 GND power_in Ground connection for power supply and signal return paths.
25 GND power_in Ground connection for power supply and signal return paths.
26 GND power_in Ground connection for power supply and signal return paths.
27 GND power_in Ground connection for power supply and signal return paths.
28 RFC bidirectional RF common port of SPDT switch; connects to RF1 or RF2 based on V1 control signal; operates 30 MHz-2.7 GHz; must be at 0 VDC without DC blocking capacitors.
29 GND power_in Ground connection for power supply and signal return paths.
30 GND power_in Ground connection for power supply and signal return paths.
31 GND power_in Ground connection for power supply and signal return paths.
32 GND power_in Ground connection for power supply and signal return paths.
33 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
