SYRACUSE, N.Y., June 9, 2009 (GLOBE NEWSWIRE) -- Anaren, Inc. (Nasdaq:ANEN) announced it has introduced an application note and layout package to facilitate the use of its halogen-free baluns in conjunction with two Analog Devices, Inc. high-speed, analog-to-digital data converter models AD9445 (14bit) and AD9446 (16bit). According to Anaren, its baluns (part numbers BD0205F5050AHF and BD0310E5050AHF) save PCB space, improve gain flatness, and improve spurious free dynamic range (SFDR) when used in conjunction with the Analog Devices data converters.
Analog Devices model AD9445 operates at up to 100 MSPS and is typically used for instrumentation, medical imaging, and radar receivers employing baseband (less than 100 MHz) IF frequencies. Model AD9445 operates at a 125 MSPS conversion rate and is optimized for multi-carrier, multimode receivers such as those found in cellular infrastructure equipment and very high-end instrumentation. In both cases, Anaren's baluns assist with improving gain flatness and SFDR performance, in addition to:
-- significant space savings (a 80 to 90% smaller footprint) over
wire-wound models;
-- improved and highly repeatable performance (when compared to
traditional wirewound equivalents), attributable to Anaren's
unique, multilayer organic substrate construction;
-- a reduced overall component count, since a single, surface-
mountable Anaren balun replaces multiple wire-wound parts
"We're excited to have had the opportunity to work with the Analog Devices team to arrive at a balun solution optimized for their high-performance data converters," said Anaren Consumer Components Group product line manager, Shawn Halpin. "From both a performance and form-factor standpoint, we're confident manufacturers using Analog Devices' converters will appreciate the advantages of our true surface mount alternative to bulky, traditional baluns," added Halpin.
Key specifications for Anaren's two baluns are as follows:
