Product Specification PE83502 Product Description The PE83502 is a high-performance monolithic UltraCMOS™ prescaler with a fixed divide ratio of 4. Its operating frequency range is 1.5 GHz to 3.5 GHz. The PE83502 operates on a nominal 3 V supply and draws only 12 mA. It is packaged in a small 8-lead MSOP and is ideal for microwave PLL synthesis solutions. The PE83502 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.

Pin Configuration (Top View) Electrostatic Discharge (ESD) Precautions When handling this UltraCMOS™ 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.

Device Functional Considerations The PE83502 takes an input signal frequency from 1.5 GHz to 3.5 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 pin 3 be supplied with a bypass capacitor to ground. In addition, the input and output signals (pins 2 & 7, respectively) need to be AC coupled via an external capacitor as shown in the test circuit in Figure 4. The ground pattern on the board should be made as wide as possible to minimize ground impedance. 3 DEC 4 5 6 7 8 GND GND GND OUT GND Table 3.

On this board, the device input (pin 2) is connected to connector J1 through a 50 Ω transmission line. A series capacitor (C3) provides the necessary DC block for the device input. It is important to note that the value of this capacitance will impact the performance of the device. A value of 15pF was found to be optimal for this board layout; other applications may require a different value. The device output (pin 7) is connected to connector J3 through a 50 Ω transmission line. A series capacitor (C1) provides the necessary DC block for the device output. Note that this capacitor must be chosen to have a low impedance at the desired output frequency the device. The value of 100pF was chosen to provide a wide operating range for the evaluation board. The board is constructed of a two-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 above ground plane model with trace width of 0.030”, trace gaps of 0.007”, dielectric thickness of 0.028”, metal thickness of 0.0014” and εr of 4.4. Note that the predominate mode for these transmission lines is coplanar waveguide. J2 provides DC power to the device. Starting from the lower left pin, the second pin to the right (J2-3) is connected to the device VDD pin (1). Two decoupling capacitors (10 pF, 1000 pF) are included on this trace. It is the responsibility of the customer to determine proper supply decoupling for their design application. The DEC pin (3) must be connected to a low impedance AC ground for proper device operation. On the board, two decoupling capacitors (C6 = 10 nF, C4 = 10 pF), located on the back of the board, perform this function.
