| Product Specification PE4242 SPDT UltraCMOSTM RF Switch Product Description The PE4242 UltraCMOSTM RF Switch is designed to cover a broad range of applications from near DC through 3000 MHz. This reflective switch integrates on-board CMOS control logic with a low voltage CMOS-compatible control interface, and can be controlled using either single-pin or complementary control inputs. Using a nominal +3-volt power supply voltage, a typical input 1 dB compression point of +27 dBm can be achieved. The PE4242 UltraCMOSTM RF Switch is manufactured in Peregrine's patented Ultra Thin Silicon (UTSi(R)) CMOS process, offering the performance of GaAs with the economy and integration of conventional CMOS.

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, UltraCMOSTM devices are immune to latch-up. Note 1: All RF pins must be DC blocked with an external series capacitor or held at 0 VDC.

Single-pin Control Logic Truth Table Control Voltages Pin 6 (VDD) = VDD Pin 4 (CTRL) = Low Pin 6 (VDD) = VDD Pin 4 (CTRL) = High Signal Path RFC to RF1 Control Logic Input The PE4242 is a versatile RF CMOS switch that supports two operating control modes; single-pin control mode and complementary-pin control mode. 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 on pin 6 (VDD). This mode of operation reduces the number of control lines required and simplifies the switch control interface typically derived from a CMOS Processor I/O port. Complementary-pin control mode allows the switch to operate using complementary control pins CTRL and CTRL (pins 4 & 6), that can be directly driven by +3-volt CMOS logic or a suitable Processor I/O port. This enables the PE4242 to be used as a potential alternate source for SPDT RF switch products used in positive control voltage mode and operating within the PE4242 operating limits.

The RF common port is connected through a 50 transmission line to the top left SMA connector, J1. Port 1 and Port 2 are connected through 50 transmission lines to the top two SMA connectors on the right side of the board, J3 and J2, respectively. A through transmission line connects SMA connectors J4 and J5. 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 with ground plane model using a trace width of 0.0476", trace gaps of 0.030", dielectric thickness of 0.028", metal thickness of 0.0021" and r of 4.4. J6 provides a means for controlling DC and digital inputs to the device. Starting from the lower left pin, the second pin to the right (J6-3) is connected to the device V1 or CTRL input. The fourth pin to the right (J6-7) is connected to the device V2 or CTRL/VDD input. Figure 4. Evaluation Board Layout Peregrine Specification 101/0083 Figure 5.
