Product Description
The Honeywell HRF-AT4510 is
a
5-bit digital
attenuator that is ideal for use in broadband
communication system applications that require
accuracy, speed and low power consumption. The
HRF-AT4510 is manufactured with Honeywell's
patented Silicon On Insulator (SOI) CMOS
HRF-AT4510 in VQFN Package
manufacturing
technology, which provides the
performance of GaAs with the economy and
integration capabilities of conventional CMOS.
RF Electrical Specifications @ + 25oC
Results @ Vdd = 5.0 +/- 10%, Vss = 0 unless otherwise stated, Z0 = 50 Ohms
