Hittite's High Resolution IF and RF Digital Attenuators to 6 GHz
New 6-Bit and 7-Bit Digital Attenuators Feature 0.25 dB Resolution
MA, December 17, 2009 – Hittite Microwave Corporation, the world class supplier of complete MMIC based
solutions for communication & military markets, has introduced two new SMT packaged high resolution 6-Bit and
7-bit Digital Attenuators which are ideal for automotive, broadband, cellular/3G, WiMAX/4G, military and test &
measurement equipment applications from DC to 6 GHz.
HMC792LP4E is a digitally controlled GaAs MMIC Digital Attenuator which operates from DC to 6 GHz, and can be
programmed to provide up to 15.75 dB attenuation with 0.25 dB resolution. The
HMC792LP4E delivers insertion loss as low as 2.2 dB, and IP3 up to +55 dBm in any state. This high linearity
Digital Attenuator also features a flexible CMOS/ TTL compatible control interface which accepts serial, parallel,
or latched parallel control inputs.
HMC759LP3E is a 7-bit BiCMOS Digital Attenuator which operates from 10 to 300 MHz, and can be programmed to
provide up to 31.75 dB attenuation in 0.25 dB steps. This versatile digital attenuator exhibits excellent
attenuation accuracy, and delivers P1dB and output IP3 of up to +21 dBm and +40 dBm respectively. The
HMC759LP3E features a CMOS/TTL compatible serial control interface, user selectable power up states, and a
serial output port for cascading other Hittite serially controlled components.
HMC792LP4E is housed in a RoHS compliant 4x4 mm QFN leadless package while the
HMC759LP3E is housed in a RoHS compliant 3x3 mm QFN leadless package. These new high performance control
products complement Hittite’s broad line of Digital Attenuators and Digital Variable Gain Amplifiers for IF and RF
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
