www.DataSheet4U.com Product Specification PE4242 SPDT UltraCMOS™ RF Switch Product Description The PE4242 UltraCMOS™ RF Switch is designed to cover a broad range of applications from near DC through 3000 MHz. This reflective switch integrates on-board CMOS control logic with a low voltage CMOS-compatible control interface, and can be controlled using either single-pin or complementary control inputs. Using a nominal +3-volt power supply voltage, a typical input 1 dB compression point of +27 dBm can be achieved. The PE4242 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.

Although this device contains circuitry to protect it from damage due to ESD, precautions should be taken to avoid exceeding the specified rating. Latch-Up Avoidance Unlike conventional CMOS devices, UltraCMOS™ devices are immune to latch-up. Note 1: All RF pins must be DC blocked with an external series capacitor or held at 0 VDC. ©2005 Peregrine Semiconductor Corp. All rights reserved.

Single-pin Control Logic Truth Table Control Voltages Pin 6 (VDD) = VDD Pin 4 (CTRL) = Low Pin 6 (VDD) = VDD Pin 4 (CTRL) = High Signal Path RFC to RF1 Control Logic Input The PE4242 is a versatile RF CMOS switch that supports two operating control modes; single-pin control mode and complementary-pin control mode. Single-pin control mode enables the switch to operate with a single control pin (pin 4) supporting a +3-volt CMOS logic input, and requires a dedicated +3-volt power supply connection on pin 6 (VDD). This mode of operation reduces the number of control lines required and simplifies the switch control interface typically derived from a CMOS µProcessor I/O port. Complementary-pin control mode allows the switch to operate using complementary control pins CTRL and CTRL (pins 4 & 6), that can be directly driven by +3-volt CMOS logic or a suitable µProcessor I/O port. This enables the PE4242 to be used as a potential alternate source for SPDT.
