Product Specification PE4240 SPST UltraCMOS™ CATV Switch DC - 1300 MHz Product Description The PE4240 is a high-isolation MOSFET Switch designed for CATV applications, covering a broad frequency range from DC up to 1.3 GHz. 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 PE4240 provides for a cost effective and manufacturable solution vs. mechanical relays. The PE4240 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.

Page 2 of 8 V Control Voltage Low 0 30% VDD V Device Description The PE4240 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 (>44 dB at 1 GHz, 85 dB at 5 MHz), high compression point, and an integrated 75-ohm terminations make the PE4240 an ideal, low cost solution. Figure 4.

Control Logic Truth Table Control Voltage (CTRL) 1 Signal Path (RF1 to RF2) High ON Low OFF Notes: 1. CTRL accepts both CMOS and TTL voltage leads. 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.)

The RF1 port is connected through a 75 Ω transmission line to the top left BNC connector, J1. The RF2 port is connected through a 75 Ω transmission line to the BNC connector on the top right side of the board, J2. A through transmission line connects BNC connectors J3 and J4. This transmission line can be used to estimate the loss of the PCB over the environmental conditions being evaluated. Figure 11. Evaluation Board Layouts Peregrine Specification 101/0079 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 εR of 4.3. Note that the predominate mode for these transmission lines is coplanar waveguide with a ground plane. J5 provides a means for controlling DC and digital inputs to the device. Starting from the lower left pin, the second pin to the right (J5-3) is connected to the device VDD input. The fourth pin to the right (J5-7) is connected to the device CTRL input. It is the responsibility of the customer to determine proper supply decoupling for their design application. Removing these components from the evaluation board has not been shown to degrade RF performance. Document No. 70-0067-03 │ www.psemi.com Figure 12.
