Chelmsford, 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.
The 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.
The HMC624LFLP4E is housed in a RoHS compliant 4 x 4 mm QFN leadless package, and requires no external matching components. The HMC624LFLP4E 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 www.hittite.com.
