SAN JOSE, Calif. -- (Business Wire)
Integrated Device Technology, Inc. (IDT®)
(NASDAQ:IDTI) announced today that it has expanded its advanced RF
silicon solutions with the addition of two new Glitch-FreeTM
digital step attenuators (DSAs), as well as its first product in a new
family of voltage variable attenuators (VVAs). These next-generation
attenuators feature wide bandwidths, low insertion loss, high linearity,
pinpoint attenuation accuracy, and a wide temperature range. Pin
compatible with competitor devices, these products are designed to meet
the stringent demands of wireless infrastructure, point-to-point
microwave, satellite communications systems and general purpose
communication infrastructure applications.

The 6-bit F1912
and 7-bit F1956
DSAs feature IDT’s industry-first breakthrough Glitch-Free technology,
which eliminates attenuation setting overshoot (glitches) from the
transmit and/or receive paths by reducing transient “glitches” during
most significant bit (MSB) transitions by up to 95 percent. Glitch-Free
response enables customers to simplify their software interface, improve
reliability, prevent damage to expensive sub-assemblies such as power
amplifiers, and limit over-ranging of data converter inputs.
The F2250
is the first in a new family of VVAs and features a frequency range of
50 – 6000MHz, an insertion loss of 1.4dB at 2GHz, high IP3I
linearity of 65dBm and wide temperature range of -40 to 105C. The Vmode
feature allows customers to select either positive or negative
attenuation control with a highly linear-in-dB attenuation
characteristic.
“Continuously evolving system requirements have driven the rapid
expansion of IDT’s RF product portfolio. These new attenuator products
offer customers a compelling upgrade path toward better linearity,
higher reliability, and lower solution cost,” said Chris Stephens,
general manager of IDT’s RF division. “These new drop-in compatible
attenuators allow development engineers to exceed evolving system
requirements with maximum re-use of existing printed circuit boards.”
Pricing and Availability
The 1000 unit prices are: F1912 = $2.03, F1956 = $2.54 and F2250 =
$2.59. Samples and evaluation kits are available for all products
immediately. Production quantities for F1912 and F1956 will be available
June 23, 2015 and F2250 production quantities will be available on May
22, 2015.
