PE4312 Datasheet, PDF (1/13 Pages) Pasternack Enterprises, Inc. – MHV Female Bulkhead Connector Solder Attachment Turret Terminal, .537 inch D Hole

Product Description
The PE4312 is a 50Ω, HaRP™ technology-enhanced 6-bit
RF Digital Step Attenuator (DSA) designed for use in
3G/4G wireless infrastructure and other high performance
RF applications.
This DSA is a pin-compatible upgraded version of the
PE4302 with higher linearity, improved attenuation
accuracy and faster switching speed. An integrated digital
control interface supports both serial and parallel
programming of the attenuation, including the capability to
program an initial attenuation state at power-up.
Covering a 31.5 dB attenuation range in 0.5 dB steps, it
maintains high linearity and low power consumption from
1 MHz through 4 GHz. PE4312 also features an external
negative supply option, and is offered in a 20-lead 4x4 mm
QFN package. In addition, no external blocking capacitors
are required if 0V DC is present on the RF ports.
The PE4312 is manufactured on Peregrine’s UltraCMOS^®
process, a patented variation of silicon-on-insulator (SOI)
technology on a sapphire substrate.
Peregrine’s HaRP™ technology enhancements deliver
high linearity and excellent harmonics performance. It is an
innovative feature of the UltraCMOS^® process, offering the
performance of GaAs with the economy and integration of
conventional CMOS.
