The rate at which the PE42851 can be switched is only limited to the switching time (Table 1) if an external negative supply is provided (pin 16 = VssEXT). Switching frequency describes the time duration between switching events. Switching time is the time duration between the point the control signal reaches 50% of the final value and the point the output signal reaches within 10% or 90% of its target value. Optional External Vss Control (VssEXT) Notes: 1. Supply biased 2. Human Body Model (MIL-STD 883 Method 3015) 3. Machine Model (JEDEC JESD22-A115) 4. Charged Device Model (JEDEC JESD22-C101) For proper operation, the VssEXT control pin must be grounded or tied to the Vss voltage specified in Table 3. When the VssEXT control pin is grounded, FETs in the switch are biased with an internal voltage generator. For applications that require the lowest possible spur performance, VssEXT can be applied externally to bypass the internal negative voltage generator. Exceeding absolute maximum ratings may cause permanent damage. Operation should be restricted to the limits in the Operating Ranges table. Operation between operating range maximum and absolute maximum for extended periods may reduce reliability. Spurious Performance Electrostatic Discharge (ESD) Precautions Table 5. Truth Table 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 rating specified. Latch-Up Avoidance Unlike conventional CMOS devices, UltraCMOS® devices are immune to latch-up. Moisture Sensitivity Level The Moisture Sensitivity Level rating for the 5x5 mm QFN package is MSL3. ©2012-2013 Peregrine Semiconductor Corp. All rights reserved. Page 4 of 12 The typical spurious performance of the PE42851 is -130 dBm when VssEXT = 0V (pin 16 = GND). If further improvement is desired, the internal negative voltage generator can be disabled by setting VssEXT = -3.4V.

Page 7 of 12 PE42851 Product Specification Thermal Data Though the insertion loss for this part is very low, when handling high power RF signals, the junction temperature rises significantly. Table 6. Theta JC Parameter Theta JC (+85°C) Min Typ 20 Max Unit C/W VSWR conditions that present short circuit loads to the part can cause significantly more power dissipation than with proper matching. Special consideration needs to be made in the design of the PCB to properly dissipate the heat away from the part and maintain the 85°C maximum case temperature. It is recommended to use best design practices for high power QFN packages: multi-layer PCBs with thermal vias in a thermal pad soldered to the slug of the package. Special care also needs to be made to alleviate solder voiding under the part. ©2012-2013 Peregrine Semiconductor Corp. All rights reserved.

Evaluation Board Layouts The PE42851 Evaluation Kit board was designed to ease customer evaluation of the PE42851 RF switch. The evaluation board in Figure 23 was designed to test the part in the 5T configuration. DC power is supplied through J10, with VDD on pin 9, and GND on the entire lower row of even numbered pins. To evaluate a switch path, add or remove jumpers on V1 (pin 3), V2 (pin 5), and V3 (pin 7) using Table 5 (adding a jumper pulls the CMOS control pin low and removing it allows the on-board pull-up resistor to set the CMOS control pin high). Pins 11 and 13 of J10 are N/C. The ANT port is connected through a 50Ω transmission line via the top SMA connector, J1. RX and TX paths are also connected through 50Ω transmission lines via SMA connectors. A 50Ω through transmission line is available via SMA connectors J8 and J9. This transmission line can be used to estimate the loss of the PCB over the environmental conditions being evaluated. An open-ended 50Ω transmission line is also provided at J7 for calibration if needed. Narrow trace widths are used near each part to improve impedance matching.
