Product Specification PE4245 SPDT UltraCMOS RF Switch Product Description DC - 4000 MHz The PE4245 RF Switch is designed to cover a broad range of Features applications from near DC to 4000 MHz. This switch integrates Single 3.0 V Power Supply on-board CMOS control logic with a low voltage CMOS compatible control input. Using a +3-volt nominal power Low insertion loss: 0.6 dB at 1000 MHz, supply voltage, a 1 dB compression point of +27 dBm can be 0.7 dB at 2000 MHz achieved. The PE4245 also exhibits excellent isolation of High isolation of 42 dB at 1000 MHz, better than 42 dB at 1000 MHz and is offered in a small 3x3 32 dB at 2000 MHz mm DFN package. Typical 1 dB compression of +27 dBm The PE4245 is manufactured on Peregrines UltraCMOS process, a patented variation of silicon-on-insulator (SOI) Single-pin CMOS logic control technology on a sapphire substrate, offering the performance Available in a 6-lead DFN package of GaAs with the economy and integration of conventional CMOS.
