Product Specification
PE4245
Product Description
The PE4245 RF Switch is designed to cover a broad range of applications from near DC to 4000 MHz. 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 PE4245 also exhibits excellent isolation of better than 42 dB at 1000 MHz and is offered in a small 3x3 mm DFN package. The PE4245 is manufactured on Peregrine’s UltraCMOS™ process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS.

Electrostatic Discharge (ESD) Precautions When handling this UltraCMOS™ device, observe the same precautions that you would use with other ESD-sensitive devices. Although this device contains circuitry to protect it from damage due to ESD, precautions should be taken to avoid exceeding the rating specified in Table 4. Latch-Up Avoidance Unlike conventional CMOS devices, UltraCMOS™ devices are immune to latch-up.

Product Specification
Evaluation Kit
The SPDT Switch Evaluation Kit board was designed to ease customer evaluation of the PE4245 SPDT switch. 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, J2 and J3. 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. 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 CNTL input. The fourth pin to the right (J6-7) is connected to the device VDD input.
