Richardson RFPD Introduces New 2-Bit, 18 dB, 35–6000 MHz UltraCMOS Digital Step Attenuator From Peregrine

DSA offers fast 29 ns switching time for 3G/4G wireless infrastructure applications

Richardson RFPD, Inc. announced recently the availability and full design support capabilities for a new fast switching 2-bit RF digital step attenuator from Peregrine Semiconductor Corporation. 

The broadband PE43205 operates from 35 to 6000 MHz, covers an 18 dB attenuation range in 6 dB and 12 dB steps, with 29 ns switching time. It maintains high RF performance and low power consumption over the entire frequency band and is offered in a 12-lead 3x3 mm QFN package. The PE43205 does not require external blocking capacitors if 0 VDC is present on the RF ports. 

The PE43205 is designed for use in 3G/4G wireless infrastructure and other high performance RF applications. It 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. 

According to Peregrine, additional key features of the PE43205 include: 

• Low attenuation error:
  • 0.10 dB @ 2 GHz
  • 0.15 dB @ 3 GHz
• High linearity: +61 dBm IIP3 @ 1950 MHz
• Wide supply range of 2.3V to 5.5V
• 1.8V control logic compatible
• 105°C operating temperature
• ESD performance:
  • 2kV HBM on all pins
  • 100V MM on all pins
  • 1 kV CDM on all pins
