Product Description

SPDT UltraCMOS RF Switch DC - 4000 MHz The PE4237 RF Switch is designed to cover a broad range of applications from near DC to 4000 MHz. This reflective switch integrates on-board CMOS control logic driven by a single-pin, low voltage CMOS or TTL control input. Using a nominal +3-
volt power supply, a 1 dB compression point of +32 dBm can be achieved. The PE4237 also exhibits outstanding isolation of better than 43 dB at 1000 MHz and is offered in a small 3x3 mm DFN package. The PE4237 is manufactured on Peregrineْs 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. Features Single 3.0-volt power supply Low insertion loss: 0.35 dB at 1000 MHz, 0.45 dB at 2000 MHz High isolation of 43 dB at 1000 MHz, 35 dB at 2000 MHz Typical 1 dB compression point of +32 dBm Single-pin CMOS or TTL logic control Available in a 6-lead DFN package Figure 1.
