RFCommon RF1 RF2 CMOS Control Driver CTRL The PE4231 SPDT High Power UltraCMOS™ RF Switch is designed to cover a broad range of applications from DC to 1.3 GHz. This single-supply reflective switch integrates on-board CMOS control logic driven by a simple, single-pin CMOS or TTL compatible control input. Using a nominal +3-volt power supply, a typical input 1 dB compression point of +32 dBm can be achieved. The PE4231 also exhibits input-output isolation of better than 42 dB at 1.0 GHz and is offered in a small 8-lead MSOP package. The PE4231 SPDT High Power 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. Product Specification SPDT High Power UltraCMOS™ DC – 1.3 GHz RF Switch Product Description Figure 1. Functional Diagram PE4231 Features • Optimized for 75 Ω systems • Single +3-volt power supply • Low insertion loss: 0.80 dB at 1.0 GHz • High isolation: 42 dB at 1.0 GHz • Typical input 1 dB compression point of +32 dBm • Single-pin CMOS or TTL logic control • Low cost Notes: 1. Device linearity will begin to degrade below 1 MHz. 2. Measured with a 1 ns risetime, 0/3 V pulse and 500 MHz bandwidth. 3. Measured in a 50 Ω system. Figure 2. Package Type Table 1.
