Product Specification PE4244 SPDT UltraCMOS™ RF Switch Product Description Features The PE4244 UltraCMOS™ RF Switch is designed to cover a broad range of applications from DC to 3.0 GHz. This switch integrates on-board CMOS control logic with a low voltage CMOS compatible control input. Using a +3-volt nominal power supply voltage, a 1 dB compression point of +27 dBm can be achieved. The PE4244 also exhibits excellent isolation of 39 dB at 1.0 GHz and is offered in a small 8-lead MSOP package. • Single +3.0-volt Power Supply • Low Insertion loss: 0.60 dB up to 2.0 GHz • High isolation of 39 dB at 1.0 GHz, 29 dB at 2.0 GHz • Typical 1 dB compression of +27 dBm The PE4244 UltraCMOS™ RF Switch is manufactured in Peregrine’s patented Ultra Thin Silicon (UTSi®) CMOS process, offering the performance of GaAs with the economy and integration of conventional CMOS. • Single-pin CMOS logic control • Packaged in 8-lead MSOP Figure 2.

The RF common port is connected through a 50 Ω transmission line to the top left SMA connector, J1. Port 1 and Port 2 are connected through 50 Ω transmission lines to the top two SMA connectors on the right side of the board, J3 and J4. A through transmission line connects SMA connectors J6 and J8. This transmission line can be used to estimate the loss of the PCB over the environmental conditions being evaluated. Figure 4. Evaluation Board Layout Peregrine specification 101/0037 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 0.030”, trace gaps of 0.007”, dielectric thickness of 0.028”, metal thickness of 0.0014” and εr of 4.4. J2 provides a means for controlling DC and digital inputs to the device. Starting from the lower left pin, the second pin to the right (J2-3) is connected to the device CTRL input. The fourth pin to the right (J2-7) is connected to the device VDD input. A decoupling capacitor (100 pF) is provided on both CTRL and VDD traces. It is the responsibility of the customer to determine proper supply decoupling for their design application. Removing these components from the evaluation board has not been shown to degrade RF performance. Figure 5.
