RF2 2-way Splitter ew 6 CATVin Description si Pin No. PE4271 Device Description The PE4271 high isolation SPST CATV Switch is designed to support CATV applications such as premium channel service connect/disconnect switch blocks. 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.)

Evaluation Board Schematic Peregrine Specification 102/0245 N ot fo rn ew 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. Peregrine Specification 101/0167 (with F connectors) si 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. de Evaluation Kit Document No. 70-0149-05 www.psemi.com (c)2005-2009 Peregrine Semiconductor Corp.
