Complementary-pin control mode. A complementary CMOS control signal to V1 is supplied to this pin. 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 in Table 3. Figure 4.

RFC to RF2 Table 6. Complementary-pin Control Logic Truth Table Control Voltages Control Logic Input Signal Path RFC to RF1 RFC to RF2 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 (pin 6). 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. Complementary-pin control mode allows the switch to operate using complementary control pins V1 and V2 (pins 4 & 6), that can be directly driven by +3-volt CMOS logic or a suitable µProcessor I/O port. This enables the PE4273 to operate in positive control voltage mode within the PE4273 operating limits. ©2005 Peregrine Semiconductor Corp. All rights reserved. Page 3 of 10 PE4273 Product Specification Evaluation Kit The SPDT Switch Evaluation Kit board was designed to ease customer evaluation of the PE4273 SPDT switch. The RF common port is connected through a 75 Ω transmission line to the bottom F connector, J2. Port 1 and Port 2 are connected through 75 Ω transmission lines to two F connectors on either side of the board, J3 and J1. A through transmission line connects F connectors J4 and J5. This transmission line can be used to estimate the loss of the PCB over the environmental conditions being evaluated. Figure 5. Evaluation Board Layouts Peregrine Specification 101/0245 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 0.021”, trace gaps of 0.030”, dielectric thickness of 0.028”, copper thickness of 0.0021” and εr of 4.3. J6 and J7 provide a means for controlling the DC inputs to the device. The lower left header (J6) is connected to the device V1 input. The lower right header (J7) is connected to the device V2 input. Series resistors (R1 and R2) are provided to reduce the package resonance between RF and DC lines. Footprints for decoupling capacitors (100 pF) are provided on both V1 and V2 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. ©2005 Peregrine Semiconductor Corp. All rights reserved. Page 4 of 10 Figure 6.
