Hittite's Widest Bandwidth SMT Digital Attenuators Operate to 33 GHz
-- New 5-Bit MMIC Attenuators Offer The Widest Bandwidth in the Industry!
MA, September 29, 2011 - Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions
for communication & military markets, has introduced two new SMT packaged MMIC 5-Bit Digital Attenuators which are
ideal for automotive, microwave radio, test equipment, military and space applications up to 33 GHz.
HMC939LP4E is a wideband SMT GaAs MMIC 5-Bit Digital Attenuator which is rated from 0.1 to 33 GHz. This
wideband attenuator product exhibits insertion loss as low as 4 dB, and can be programmed to provide up to 31 dB
attenuation in 1.0 dB steps. The
HMC941LP4E is a wideband SMT GaAs MMIC 5-Bit Digital Attenuator which is rated from 0.1 to 33 GHz. This
wideband attenuator product exhibits insertion loss as low as 4 dB, and can be programmed to provide up to 15.5 dB
attenuation in 0.5 dB steps.
HMC941LP4E feature excellent attenuation accuracy of ± 0.3 dB and fast switching speed of 90 ns, and both
accept positive control voltages of 0/+3V or 0/+5V. The
HMC941LP4E also exhibit high input IP3 performance of up to +45 dBm, allowing them to be used in various
locations within a microwave or millimeterwave transceiver. The
HMC939LP4E and the
HMC941LP4E are housed in RoHS compliant, 4 x 4 mm QFN packages.
HMC941LP4E are also offered in bare die form as the
HMC939 and the
HMC941LP4E complement Hittite’s extensive line of control components, including the widest selection of MMIC
digital attenuators available from any OEM. Samples and evaluation PC boards for all SMT packaged products are
available from stock and can be ordered via the company's e-commerce site or via direct purchase order. Released
data sheets are available on-line at www.hittite.com.
