Product Specification
Evaluation Kit Figure 5. Evaluation Board Layout
The SPDT switch EK Board was designed to ease customer evaluation of pSemi’s PE4259. The RF common port is connected through a 50Ω transmission line via the top SMA connector, J1. RF1 and RF2 are connected through 50Ω transmission lines via SMA connectors J2 and J3, respectively. A through 50Ω transmission is available via SMA connectors J4 and J5. This transmission line can be used to estimate the loss of the PCB over the environmental conditions being evaluated. 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 and J7 provide a means for controlling DC and digital inputs to the device. J6-1 is connected to the device VDD or CTRL input. J7-1 is connected to the device CTRL input.
