PE43204_14 Datasheet, PDF (1/8 Pages) Peregrine Semiconductor – 50 Ω RF Digital Attenuator | |||
|
Product Description
The PE43204 is a 50â¦, HaRPâ¢-enhanced, high linearity, 2-bit
RF Digital Step Attenuator (DSA) covering an 18 dB
attenuation range in 6 dB steps. With a parallel control
interface, it maintains high attenuation accuracy, fast switching
speed, low insertion loss and low power consumption. This
next generation Peregrine DSA is available in a 3x3 mm 12-
lead QFN footprint.
The PE43204 is manufactured on Peregrineâs UltraCMOSâ¢
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.
