2 / 6 page  Product Specification PE4244 Page 2 of 6 ©2005-2013 Peregrine Semiconductor Corp. All rights reserved. Document No. DOC-30006-2 │ UltraCMOS® RFIC Solutions Table 2. Pin Descriptions Note 1: All RF pins must be DC blocked with an external series capacitor or held at 0 VDC Figure 3. Pin Configuration (Top View) Table 3. Absolute Maximum Ratings 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. Table 4.

A bypass capacitor (100 pF) to the ground plane should be placed as close as possible to the pin 2 CTRL CMOS logic level: High = RFC to RF1 signal path Low = RFC to RF2 signal path 3 GND Ground connection. Traces should be physically short and connected to ground 4 RFC Common RF port for switch (Note 1) 5 RF2 RF2 port (Note 1) 6 GND Ground Connection. Traces should be physically short and connected to ground 7 GND Ground Connection. Traces should be physically short and connected to ground 8 RF1 RF1 port (Note 1) Symbol Parameter/Conditions Min Max Units VDD Power supply voltage -0.3 4.0 V VI Voltage on any input -0.3 VDD+ V TST Storage temperature range -65 150 °C TOP Operating temperature -40 85 °C PIN Input power (50Ω) 30 dBm VESD ESD voltage (Human Body 1500 V Parameter Min Typ Max Units VDD Power Supply Voltage 2.7 3.0 3.3 V IDD Power Supply Current VDD = 3V, VCNTL = 3V 250 500 nA Control Voltage High 0.7xVDD V Control Voltage Low 0.3xVDD V Control Voltage Signal Path CTRL = CMOS High RFC to RF1 CTRL = CMOS Low RFC to RF2 Table 5. Control Logic Truth Table Absolute Maximum Ratings are those values listed in the above table. 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. Moisture Sensitivity Level The Moisture Sensitivity Level rating for the 5x5 mm QFN package is MSL1. |
