Hittite's New High Linearity Digital Attenuator for Infrastructure Applications
-- New 6-Bit Digital Attenuator Serves IF Frequencies From 60 to 500 MHz
MA, August 8, 2011 - Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for
communication & military markets, has introduced a new 6-bit GaAs MMIC Digital Attenuator which is ideal for
Intermediate Frequency (IF) applications in automotive, broadband, cellular/3G, LTE/4G, test & measurement equipment
and military applications.
HMC624LFLP4E is a GaAs MMIC
High Linearity 6-Bit Digital Attenuator which operates from 60 to 500 MHz, and can be programmed to provide from 0.5
to 31.5 dB of relative attenuation with 0.5 dB resolution. The
HMC624LFLP4E exhibits low
insertion loss of 1.2 dB, high input IP3 of +55 dBm, and outstanding accuracy of 0.1 dB step error. The dual mode
control interface is CMOS/TTL compatible, and accepts either a three-wire serial input or a 6 bit parallel word with
either 0/+3V or 0/+5V logic for added flexibility. The
HMC624LFLP4E also features
user selectable power up states and a serial output for cascading other Hittite serially controlled components.
HMC624LFLP4E is housed in a
RoHS compliant 4 x 4 mm QFN leadless package, and requires no external matching components. The
complements Hittite’s broad line of MMIC analog and digital attenuators which are available in die, SMT and module
formats, and serve IF and RF applications to 40 GHz.
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
