| Advance Information PE9308 Product Description The PE9308 is a high-performance dynamic UltraCMOSTM prescaler ideal for Ku band Transceiver applications. It has a fixed divide ratio of 4 with an operating frequency range of 4.0 GHz to 13.5 GHz. The PE9308 operates on a nominal 2.6 V supply and draws only 15 mA. It is packaged in a small 8-lead Flat Pack and is also available in Die form for Hybrid application. The PE9308 is manufactured in Peregrine's patented Ultra Thin Silicon (UTSi(c)) CMOS process, offering the performance of GaAs with the economy and integration of conventional CMOS. 13.5 GHz Low Power UltraCMOSTM Divide-by-4 Prescaler for RAD-Hard Space Applications Features * High-frequency operation: up to 13.5 GHz * Fixed divide ratio of 4 * Low-power operation:15 mA typical @ 2.6V * SEL Immune due to UltraCMOSTM * SEU <10-10 errors / bit-day * 100 Krads (Si) Total Dose * Small package: 8-lead Formed Flat pack * Available as Die Figure 1.

Pin Configuration (Top View) 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. Device Functional Considerations VDD1 1 2 8 7 NC VDD1 RF IN NC PE9308 3 4 6 5 RF OUT VDD2 NC Table 2.

Not connected Not connected The PE9308 takes an input signal frequency from between 4.0 GHz to 13.5 GHz and produces an output signal frequency one-fourth that of the supplied input. In order for the prescaler to work properly, several conditions need to be adhered to. It is crucial that pins 1, 2 and 5 be supplied with a bypass capacitor to ground. In addition, the output signal (pins 6) needs to be ac coupled via an external capacitor as shown in the test circuit below. The ground pattern on the board should be made as wide as possible to minimize ground impedance. Table 3.

On this board, the device input (pin 3) is connected to the SMA connector J2 through a 50 transmission line. The device output (pin 6) is connected to SMA connector J3 through a 50 transmission line. J1 provides DC power to the device via pin 1,2,4,5,7,8.Multiple decoupling capacitors (C4,5,8,9=10pF, C3,6,7,10=0.01uF) are used. It is the responsibility of the customer to determine proper supply decoupling for their design application. The board is constructed using 4 layers. The top and bottom layers are comprised of Rogers low loss 4350 material having a core thickness of 0.010"; while the internal layers are comprised of FR-4. The overall board thickness is 0.062".
