Single-pin control mode enables the switch to operate with a single control pin (pin 4) supporting a +3V CMOS logic input, and requires a dedicated +3V power supply connection on pin 6 (VDD). This mode of operation reduces the number of control lines required and simplifies the switch control interface typically derived from a CMOS  Processor I/O port. Complementary-pin control mode allows the switch to operate using complementary control pins CTRL and CTRL (pins 4 & 6), that can be directly driven by +3V CMOS logic or a suitable  Processor I/O port. This enables the PE4239 to be used as a potential alternate source for SPDT RF switch products used in positive control voltage mode and operating within the PE4239 operating limits. ©2021 pSemi Corporation All rights reserved.

The RF common port is connected through a 50Ω transmission line to the top left SMA connector, J1. Port 1 and Port 2 are connected through 50Ω transmission lines to the top two SMA connectors on the right side of the board, J3 and J2, respectively. A through transmission line connects SMA connectors J4 and J5. This transmission line can be used to estimate the loss of the PCB over the environmental conditions being evaluated. Figure 4. Evaluation Board Layout PSemi Specification 101/0083 The board is constructed of a two metal layer FR4 material with a total thickness of 0.031”. The bottom layer provides ground for the RF transmission lines. The transmission lines were designed using a coplanar waveguide with ground plane model using a trace width of 0.0476”, trace gaps of 0.030”, dielectric thickness of 0.028”, metal thickness of 0.0021” and εr of 4.4. J6 provides a means for controlling DC and digital inputs to the device. Starting from the lower left pin, the second pin to the right (J6-3) is connected to the device V1 or CTRL input. The fourth pin to the right (J6-7) is connected to the device V2 or CTRL/VDD input. Figure 5. Evaluation Board Schematic PSemi Specification 102/0104 ©2021 pSemi Corporation All rights reserved.
