Attenuators feature digital control
Two new GaAs MMIC digital attenuators, with TTL/CMOS control, are ideal for wireless infrastructure, test equipment and microwave radio applications from DC to 3.0GHz.
Hittite Microwave has released two new GaAs MMIC digital attenuators, with TTL/CMOS control, which are ideal for wireless infrastructure, test equipment, and microwave radio applications from DC to 3.0GHz The HMC470LP3 is a 5bit digital attenuator with a typical insertion loss of 1.4dB and will provide any attenuation state from 1dB LSB to 31dB with a typical step error of +/-0.2dB

Cores have lower losses at high frequencies
Chang Sung Corp of Korea offers a complete range of toroids in MPP, high-flux and Sendust powder materials manufactured to the highest specifications.
The HMC472LP4 is a 6bit digital attenuator with a typical insertion loss of 1.5dB and will provide any attenuation state from 0.5dB LSB to 31.5dB with a typical step error of +/-0.3dB.
These new digital attenuators offer lower insertion loss, faster switching speed and operation down to near DC without the need for an internally generated or externally supplied negative voltage.
Both attenuators are matched to 50ohm at all attenuation levels, deliver minimal phase shift per bit and are TTL/CMOS compatible, requiring only a single control line per bit.
These low cost, low loss digital attenuators are housed in industry standard QFN leadless surface mount packages.
Samples and evaluation PC boards are available from MRC Components.
