Product Description
The PE42430 is a HaRP™-enhanced reflective SP3T RF switch developed on the UltraCMOS® process technology. This tiny general purpose switch is ideal for WLAN and bluetooth applications in the 2.4 - 2.5 GHz bands as well as general broadband switching applications. It is comprised of three RF ports and has low insertion loss and high isolation. An on-chip CMOS decode logic facilitates a three-pin CMOS control interface. Unlike competitive solutions, there is no need for blocking capacitors when using the PE42430.
pSemi’s HaRP™ technology enhancements deliver high linearity and exceptional harmonics performance. It is an innovative feature of the UltraCMOS® process, providing performance superior to GaAs with the economy and integration of conventional CMOS.

Notes: 1. Specifications under min and max nominal conditions 2. Please refer to Maximum Input Power (50 Ω ) in Table 4. 3. Switching time is measured while the part is powered on and one of the control pins is switching state. 4. Turn on time is defined as the time it takes the part to go from an unpowered state to 90% RF voltage. Max power can only be applied after the part is turned on/ 5. Video feedthrough is measured by terminating all ports and measuring peak transients while switching logic state.
