| Product Specification PE4271 Product Description The PE4271 is a is a high-isolation Switch designed for CATV applications, covering a broad frequency range from near DC up to 3000 MHz. This single-supply SPST switch offers a single-pin CMOS control interface with industry leading CTB performance. It also provides low insertion loss, high isolation and extremely low bias requirements while operating on a single 3-volt supply. In a typical CATV application, the PE4271 provides for a cost effective and manufacturable solution vs. mechanical relays. The PE4271 is manufactured on Peregrine's UltraCMOSTM 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.

Electrostatic Discharge (ESD) Precautions When handling this UltraCMOSTM 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. Table 3.

This function is typically performed by bulky and expensive mechanical switches. The high isolation characteristics (60 dB at 1 GHz, 85 dB at 5 MHz), high compression point, and an integrated 75 (0.25 watt) input termination make the PE4271 an ideal, low cost solution. The control logic input pin (CTRL) is typically driven by a 3-volt CMOS logic level signal, and has a threshold of 50% of VDD. For flexibility to support systems that have 5-volt control logic drivers, the control logic input has been designed to handle a 5volt logic HIGH signal. (A minimal current will be sourced out of the VDD pin when the control logic input voltage level exceeds VDD.) Document No. 70-0149-03 UltraCMOSTM RFIC Solutions 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. Latch-Up Avoidance Unlike conventional CMOS devices, UltraCMOSTM devices are immune to latch-up. (c)2005 Peregrine Semiconductor Corp. All rights reserved.

Page 4 of 8 Document No. 70-0149-03 UltraCMOSTM RFIC Solutions PE4271 Product Specification Evaluation Kit The PE4271 EK board was designed to ease customer evaluation of Peregrine's high performance SPST CATV MOSFET switch. RF1 is connected through a 75 transmission line via the top left F connector, J1. RF2 is connected through a 75 transmission line via the top right F connector, J2. A 75 through transmission line is available via F connectors J3 and J4. This transmission line can be used to estimate the loss of the PCB over the environmental conditions being evaluated. VDD is supplied via J6-2, while the control logic voltage is supplied via J5-2. It is the responsibility of the customer to determine proper supply decoupling for their design application. It has been observed that by removing C1 and C2 from the evaluation board has not shown to degrade RF performance. 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 model with trace width of 0.021", trace gaps of 0.030", dielectric thickness of 0.028", metal thickness of 0.0021" and r of 4.6. Note that the predominate mode for these transmission lines is coplanar waveguide with a ground plane. Figure 11.
