Product Specification
PE4270
Product Description
The PE4270 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 PE4270 provides for a cost effective and manufacturable solution vs. mechanical relays. The PE4270 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. Latch-Up Avoidance Unlike conventional CMOS devices, UltraCMOSTM devices are immune to latch-up.

Notes: 1. Both RF pins must be held at 0 VDC or require external DC blocking capacitors 2. The exposed pad must be soldered to the ground plane for proper switch performance.

Device Description The PE4270 high isolation SPST CATV Switch is designed to support CATV applications such as premise disconnect of a CATV signal path. This function is typically performed by bulky and expensive mechanical relays. The high isolation characteristics, high compression point, and integrated 75-ohm terminations make the PE4270 an ideal, cost effective and manufacturable product of choice. 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 5-volt logic HIGH signal. (A minimal current will be sourced out of the VDD pin when the control logic input voltage level exceeds VDD.)

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.

Evaluation Kit
The PE4270 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.
