| Product Specification PE4246 Product Description The PE4246 RF Switch is designed to cover a broad range of applications from DC to 5000 MHz. It is non-reflective at both RF1 and RF2 ports. This SPST switch integrates a single-pin CMOS control interface, and provides low insertion loss while operating with extremely low bias from a single +3-volt supply. In a typical application, the high isolation PE4246 can replace multiple RF switches of lesser isolation performance. It is offered in a small 3x3 mm DFN package. The PE4246 is manufactured on Peregrine's UltraCMOSTM 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.

Control Logic Truth Table Control Voltage CTRL = CMOS or TTL High CTRL = CMOS or TTL Low Signal Path RF1 to RF2 RF1 isolated from RF2 Notes: 1. A bypass capacitor should be placed as close as possible to the pin. 2. Both RF pins must be DC blocked by an external capacitor or held at 0 VDC. 3. The exposed pad must be soldered to the ground plane for proper switch performance. Control Logic The control logic input pin (CTRL) is typically driven by a 3-volt CMOS logic level signal, and has a threshold of 50% of VDD. For flexibility to support systems that have 5-volt control logic drivers, the control logic input has been designed to handle a 5-volt logic HIGH signal. (A minimal current will be sourced out of the VDD pin when the control logic input voltage level exceeds VDD.) Electrostatic Discharge (ESD) Precautions When handling this UltraCMOSTM 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 rating specified in Table 3. Latch-Up Avoidance Unlike conventional CMOS devices, UltraCMOSTM devices are immune to latch-up. Table 3.

Exceeding these values may cause permanent device damage. Functional operation should be restricted to the limits in the DC Electrical Specifications table. Exposure to absolute maximum ratings for extended periods may affect device reliability. (c)2005 Peregrine Semiconductor Corp. All rights reserved.

Page 4 of 8 Document No. 70-0090-05 UltraCMOSTM RFIC Solutions PE4246 Product Specification Evaluation Kit The SPST Switch Evaluation Kit board was designed to ease customer evaluation of the PE4246 SPST switch. The RF1 port is connected through a 50 transmission line to the top left SMA connector, J1. The RF2 port is connected through a 50 transmission line to the top right SMA connector, J2. A through transmission line connects SMA connectors J3 and J4. 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 model with trace width of 0.0476", trace gaps of 0.030", dielectric thickness of 0.028", metal thickness of 0.0021" and R of 4.3. Note that the predominate mode for these transmission lines is coplanar waveguide with a ground plane. J5 and J6 provide a means for controlling DC and digital inputs to the device. J6-1 is connected to the device VDD input. J5-1 is connected to the device CTRL input. J5-2 and J6-2 are GND connections. A decoupling capacitor (100 pF) is provided on both CTRL and VDD traces. It is the responsibility of the customer to determine proper supply decoupling for their design application. Removing these components from the evaluation board has not been shown to degrade RF performance. Figure 11. Evaluation Board Layouts Peregrine Specification 101/0102 Figure 12.
