Product Specification PE4241 SPDT UltraCMOS™ RF Switch Product Description Features • Single-pin or complementary CMOS logic control inputs The PE4241 UltraCMOS™ RF Switch is designed to cover a broad range of applications from DC through 3.0 GHz. 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. • +3.0-volt power supply needed for single-pin control mode • Low insertion loss: 0.7 dB at 1.0 GHz, 0.9 dB at 2.0 GHz • Isolation of 30 dB at 1.0 GHz, 21 dB at 2.0 GHz The PE4241 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. • Typical input 1 dB compression point of +27 dBm • Ultra-small SOT23 package Figure 1.

Electrostatic Discharge (ESD) Precautions When handling this UltraCMOS™ device, observe the same precautions that you would use with other ESD-sensitive devices. 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. ©2005 Peregrine Semiconductor Corp. All rights reserved.

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. RFC to RF2 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 PE4241 to be used as a potential alternate source for SPDT RF switch products used in positive control voltage mode and operating within the PE4241 operating limits. ©2005 Peregrine Semiconductor Corp.

Evaluation Board Layout Evaluation Kit The SPDT Switch Evaluation Kit board was designed to ease customer evaluation of the PE4241 SPDT switch. The RF common port is connected through a 50Ω transmission line to the top left SMA connector, J1. Port 1 and Port 2 are connected through 50Ω transmission lines to the top two SMA connectors on the right side of the board, J3 and J2, respectively. A through transmission line connects SMA connectors J4 and J5. This transmission line can be used to estimate the loss of the PCB over the environmental conditions being evaluated. The board is constructed of a two metal layer FR4 material with a total thickness of 0.031”. The bottom layer provides ground for the RF transmission lines. The transmission lines were designed using a coplanar waveguide with ground plane model using a trace width of 0.0476”, trace gaps of 0.030”, dielectric thickness of 0.028”, metal thickness of 0.0021” and εr of 4.4. J6 provides a means for controlling DC and digital inputs to the device. Starting from the lower left pin, the second pin to the right (J6-3) is connected to the device V1 or CTRL input. The fourth pin to the right (J6-7) is connected to the device V2 or CTRL/VDD input. Figure 5. Evaluation Board Schematic J3 J2 J4 ©2005 Peregrine Semiconductor Corp. All rights reserved.
