The PE42020 can accommodate up to ±10V input DC voltage on the RF ports. It can be configured as a 50 Ω absorptive or an open reflective True DC switch via the single LZ pin. The PE42020 True DC RF switch delivers excellent RF performance and high power handling down to zero Hertz, making this device ideal for handling the complex combination of DC, RF/analog and digital signals in test and measurement (T&M) and automated test equipment (ATE) applications. The PE42020 is manufactured on Peregrine’s UltraCMOS ® process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate. Peregrine’s HaRP™ technology enhancements deliver high linearity and excellent harmonics performance. It is an innovative feature of the UltraCMOS process, offering the performance of GaAs with the economy and integration of conventional CMOS.

UltraCMOS® True DC RF Switch Page 2 DOC-23814-3 – (12/2014) www.psemi.com Absolute Maximum Ratings Exceeding absolute maximum ratings listed in Table 1 may cause permanent damage. Operation should be restricted to the limits in Table 2. Operation between operating range maximum and absolute maximum for extended periods may reduce reliability. ESD Precautions When handling this UltraCMOS device, observe the same precautions as with any 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 1. Latch-up Immunity Unlike conventional CMOS devices, UltraCMOS devices are immune to latch-up.

UltraCMOS® True DC RF Switch DOC-23814-3 – (12/2014) Page 21 www.psemi.com Evaluation Kit The SPDT switch evaluation board was designed to ease customer evaluation of Peregrine's PE42020. The RF common port is connected through a 50 Ω transmission line via the SMA connector, J3. RF1 and RF2 ports are connected through 50 Ω transmission lines via SMA connectors J1 and J2 respectively. A 50 Ω through trans- mission line is available via SMA connectors J5 and J6, which can be used to de-embed the loss of the PCB. J4 provides DC and digital inputs to the device. The board is constructed of a four metal layer material with a total thickness of 62 mils. The top RF layer is Rogers 4350B material with a thickness of 6.6 mils and the Ɛ r = 3.66. The middle layers provide ground for the transmission lines. The transmission lines were designed using a coplanar waveguide with ground plane model using a trace width of 13 mils, trace gaps of 10.5 mils and metal thickness of 3.4 mils. For the true performance of the PE42020 to be realized, the PCB must be designed in such a way that RF trans- mission lines and sensitive DC I/O traces are well isolated from one another.
