PE4257. Product Specification. Product Description

Transcription

1 Product Description The PE is a high-isolation UltraCMOS Switch designed for wireless applications, covering a broad frequency range from near DC up to 000 MHz. 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 -volt supply. In a typical wireless application, the PE provides unprecedented isolation and integration. The PE 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.

Electrostatic Discharge (ESD) Precautions When handling this UltraCMOS device, observe the same precautions that you would use with other ESDsensitive devices. Although this device contains circuitry to protect it from damage due to ESD, precautions should be taken to avoid exceeding the rating specified. Switching Frequency The PE has a maximum khz switching rate when the internal negative voltage generator is used (pin =). The rate at which the PE can be switched is only limited to the switching time if an external - V supply is provided at (pin=v SS ). Table.

4 PE Evaluation Kit The SPDT Switch Evaluation Kit board was designed to ease customer evaluation of the PE SPDT switch. The RF common port is connected through a 0 Ω transmission line to J. Port and Port are connected through 0 Ω transmission lines to J and J. A through transmission line connects SMA connectors J and J. This transmission line can be used to estimate the loss of the PCB over the environmental conditions being evaluated. Figure. Evaluation Board Layouts Peregrine Specification 0/0 The board is constructed of a four metal layer FR material with a total thickness of 0.0. The transmission lines were designed using a coplanar waveguide with ground plane ( mil core,. mil width, 0mil gap). Note the number of vias surrounding the device in the layout shown in Figure. These vias are critical for obtaining the specified isolation performance for the device shown in this datasheet. J 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. When the jumper is in place, µa of current will flow through the MΩ pull up resistor. This extra current should not be attributed to the requirements of the device. Figure 9.
