Product Specification PE4280 75 Ω SPDT CATV UltraCMOS™ Switch DC—2.2 GHz Product Description The PE4280 is an UltraCMOS™ Switch designed for CATV applications, covering a broad frequency range from DC up to 2.2 GHz. This single-supply SPDT switch integrates a two-pin CMOS control interface. It also provides low insertion loss with extremely low bias requirements while operating on a single 3 V supply. In a typical CATV application, the PE4280 provides for a cost effective and manufacturable solution when compared to mechanical relays. The PE4280 is manufactured in Peregrine’s patented Ultra Thin Silicon (UTSi®) CMOS process, offering the performance of GaAs with the economy and integration of conventional CMOS. Figure 1.

Although this device contains circuitry to protect it from damage due to ESD, precautions should be taken to avoid exceeding the rating specified. Latch-Up Avoidance Unlike conventional CMOS devices, UltraCMOS™ devices are immune to latch-up. Switching Frequency The PE4280 has a maximum 25 kHz switching rate when the internal negative voltage generator is used (pin 18=GND). The rate at which the PE4280 can be switched is only limited to the switching time if an external -3 V supply is provided at pin 18 (VSS). Notes: 1. RF pins 3, 8, and 13 must be at 0 VDC. The RF pins do not require DC blocking capacitors for proper operation if the 0 VDC requirement is met. 2. Pins 16 and 17 are the CMOS controls that set the three operating states. 3. Connect pin 18 to GND to enable the on-chip negative voltage generator. Connect pin 18 to VSS (-3 V) to bypass and disable internal -3 V supply generator.

Evaluation Board Layouts Evaluation Kit The SPDT Switch Evaluation Kit board was designed to ease customer evaluation of the PE4280 SPDT switch. The RFC port is connected through a 75 Ω transmission line to J2. Port 1 and Port 2 are connected through 75 Ω transmission lines to J1 and J3. A through transmission line connects F connectors J4 and J5. This transmission line can be used to estimate the loss of the PCB over the environmental conditions being evaluated. The board is constructed of a four metal layer FR4 material with a total thickness of 0.062”. The transmission lines were designed using a coplanar waveguide with ground plane (28 mil core, 21mil width, 30 mil gap). J5 GND C2 J6-5 J6-9 J6-13 C1 J6-1 VSS/ GND Proper PCB design is essential for full isolation performance. This eval board demonstrates good trace and ground management for minimum coupling and radiation. J4 GND When the jumper is in place, 3 µA of current will flow through the 1 MΩ pull up resistor. This extra current should not be attributed to the requirements of the device. Figure 5. Evaluation Board Schematic VDD J6 provides a means for controlling DC and digital inputs to the device. The provided jumpers short the package pin to ground for logic low. When the jumper is removed, the pin is pulled up to VDD for logic high.
