Introduction


The PE42540 switch board provides one common RF connection and four selectable paths. Its small PCB footprint makes it suitable for integrating signal routing into a bench setup or custom electronics project.

Hardware Specification

  • Switch chip: PE42540, absorptive SP4T

  • RF paths: One common port and four selectable ports

  • Board size: 4.5 × 3 cm

  • Supply: Listed as 3.3 V for this board; the chip’s specified VDD range is 3.0–3.6 V

  • Connections: SMA RF connectors, according to the supplied listing

  • Frequency: Chip specified at 10 Hz–8 GHz; complete board range requires confirmation

Software Specification

  • Control: PE42540 uses a two-pin CMOS control interface to select the RF path
