Preliminary Specification PE4274 Product Description The PE4274 is an SPDT UltraCMOS™ Switch designed for Broadband applications such as CATV, DTV, Multi-Tuner DVR (Digital Video Recorder), Set-top Box, PCTV and Game Boxes. It offers high isolation and low insertion loss in both a powered and a unique unpowered default state. The PE4274 covers a broad frequency range from near DC to beyond 2.2 GHz with a single positive supply and CMOS control. The PE4274 provides a smaller, cost effective, more reliable and manufacturable alternative to mechanical relays in some set-top box applications. The PE4274 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.

Negative Supply Option 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 V DC requirement is met. 2. Pins 16 and 17 are the CMOS controls that set the four operating states. Switching Frequency The PE4274 has a maximum 25 kHz switching rate when the internal negative voltage generator is used (pin 18 = GND). The rate at which the PE4274 can be switched is only limited to the switching time if an external -3 V supply is provided at (pin 18 = VSS). 3. Connect pin 18 to GND to enable the negative voltage generator. Connect pin 18 to VSS (-3V) to bypass and disable internal -3V supply generator. See “Switching Frequency”.

The operation of the PE4274 is not supported or characterized in the C1 = High and C2 = High state. Figure 4. Typical Application Block Diagram The PE4274 provides the high isolation required by FCC part 15.115 regulation between the television antenna and the cable plant. The advantage of the PE4274 is that device isolation / thru performance is maintained when power is removed. This unique feature makes the PE4274 ideal for set-top box and VCR applications. The PE4274 supports signal flow from RFC to RF1 and RF2 termination in the unpowered state; similar to the powered state with C1=High, C2=Low.

Evaluation Board Layouts Evaluation Kit The SPDT Switch Evaluation Kit facilitates customer evaluation of the PE4274 SPDT switch. The RF common port is connected through a 75 Ω transmission line to J2. Ports 1 and 2 are connected through 75 Ω transmission lines to J1 and J3. A through line connects F connectors J4 and J5. This transmission line can be used to estimate the PCB loss over the environmental conditions. J6 provides DC and digital inputs to the device. The board is composed of a four metal layer FR4 material with a total thickness of 0.062”. The transmission lines are hybrid microstrip/coplanar waveguide with ground plane (28 mil core, 21 mil width, 30 mil gap). The provided jumpers short the control pins to ground for logic low. With the jumper removed the control input rises to VDD for logic high through the 1 MΩ pull up resistor. These resistors will draw several microamps from VDD. They are not required for normal operation. Figure 15.
