Product Specification PE42421 SPDT UltraCMOS® 10 MHz – 3.0 GHz RF Switch Product Description Features The PE42421 UltraCMOS® RF switch is designed to cover a broad range of applications from 10 MHz 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 +33.5 dBm can be achieved. Single-pin or complementary CMOS The PE42421 SPDT RF switch is manufactured on Peregrine’s UltraCMOS® process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS. logic control inputs Low insertion loss: 0.35 dB at 1000 MHz, 0.5 dB at 2000 MHz Isolation of 30 dB at 1000 MHz, 20 dB at 2000 MHz Typical input 1 dB compression point of +33.5 dBm 1.8V minimum power supply voltage SC-70 package Figure 2.

To maintain optimum device performance, do not exceed Max PIN at desired operating frequency (see Figure 4) This pin supports two interface options: Single-pin control mode. A nominal 3-volt supply connection is required. Complementary-pin control mode. A complementary CMOS control signal to CTRL is supplied to this pin. Bypassing on this pin is not required in this mode. 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. Figure 4. Maximum Input Power Note: 4.

Switching Frequency Latch-Up Avoidance Unlike conventional CMOS devices, UltraCMOS® devices are immune to latch-up. The PE42421 has a maximum 25 kHz switching rate. Electrostatic Discharge (ESD) Precautions When handling this UltraCMOS® device, observe the same precautions that you would use with other ESDsensitive devices. Although this device contains circuitry to protect it from damage due to ESD, precautions should be taken to avoid exceeding the specified rating.

Complementary-pin Control Logic Truth Table Control Voltages Pin 6 (CTRL or VDD) = Low Pin 4 (CTRL) = High Pin 6 (CTRL or VDD) = High Pin 4 (CTRL) = Low Signal Path RFC to RF2 Control Logic Input The PE42421 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. RFC to RF1 ©2010-2013 Peregrine Semiconductor Corp. All rights reserved. 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 PE42421 to be used as a potential alternate source for SPDT RF switch products used in positive control voltage mode and operating within the PE42421 operating limits.

Evaluation Board Layouts Evaluation Kit Peregrine Specification 101-0162-02 The SPDT switch EK Board was designed to ease customer evaluation of Peregrine’s PE42421. The RF common port is connected through a 50Ω transmission line via the top SMA connector, J1. RF1 and RF2 are connected through 50Ω transmission lines via SMA connectors J2 and J3, respectively. A through 50Ω transmission is available via 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 εr of 4.4. J6 and J7 provide a means for controlling DC and digital inputs to the device. J6-1 is connected to the device VDD or CTRL input. J7-1 is connected to the device CTRL input. Figure 6.
