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. 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 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 32lead 5 × 5 mm QFN package is MSL3. Optional External VSS Control (VSS_EXT) For applications that require a faster switching rate or spur-free performance, this part can be operated in bypass mode. Bypass mode requires an external negative voltage in addition to an external VDD supply voltage. As specified in Table 3, the external negative voltage (VSS_EXT) when applied to pin 16 will disable and bypass the internal negative voltage generator. Switching Frequency The PE42820 has a maximum 25 kHz switching rate in normal mode (pin 16 = GND). A faster switching rate is available in bypass mode (pin 16 = VSS_EXT). The rate at which the PE42820 can be switched is then limited to the switching time as specified in Table 1. 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. Spurious Performance The typical low-frequency spurious performance of the PE42820 in normal mode is –137 dBm (pin 16 = GND). If spur-free performance is desired, the internal negative voltage generator can be disabled by applying a negative voltage to VssEXT (pin 16). Hot Switching Capability The typical hot switching capability of the PE42820 is +30 dBm. Hot switching occurs when RF power is applied while switching between RF ports. ©2012-2015 Peregrine Semiconductor Corp. All rights reserved.

Page 7 of 12 PE42820 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. ©2012-2015 Peregrine Semiconductor Corp. All rights reserved.

Evaluation Board Layout The PE42820 evaluation kit board was designed to ease customer evaluation of the PE42820 RF switch. The evaluation board in Figure 14 was designed to test the part. 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) using Table 5. The ANT port is connected through a 50Ω transmission line via the top SMA connector, J1. RF1 and RF2 paths are also connected through 50Ω transmission lines via SMA connectors as J2 and J3. A 50Ω through transmission line is available via SMA connectors J5 and J6. 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 J4 for calibration if needed. Narrow trace widths are used near each part to improve impedance matching. The shunt C1 on RFC port is to provide for high frequency impedance matching. PRT-10605 Document No. DOC13614-4 │ www.psemi.com ©2012-2015 Peregrine Semiconductor Corp. All rights reserved.
