The HMC629ALP4ETR from Analog Devices is a broadband 4-bit GaAs MMIC digital attenuator designed for RF and IF applications. It operates over a frequency range of DC to 10GHz, providing a maximum attenuation of 45dB. The attenuator features low insertion loss, with a typical value of 2.25 dB from DC to 6 GHz and 3.75 dB from 6 to 10 GHz.
This versatile digital attenuator incorporates a dual-mode control interface that is CMOS/TTL compatible, accepting either a three-wire serial input or a 4-bit parallel word. It is housed in a compact 4x4 mm QFN leadless package, suitable for surface mount assembly and requiring no external matching components.
Typical applications for the HMC629ALP4ETR include cellular infrastructure, WiBro/WiMAX/4G systems, microwave radio, VSAT, test equipment, and sensors. It supports single +3V or +5V supply operation and offers features like power-up state selection and typical step error of ±0.25 dB.
