The HMC629ALP4E is a broadband 4-bit GaAs MMIC digital attenuator designed for RF and IF applications. It operates over a frequency range of DC to 10 GHz, providing a maximum attenuation of 45 dB with a characteristic impedance of 50 Ohms.
Key electrical specifications include a typical insertion loss of 2.25 dB from DC to 6 GHz and 3.75 dB from 6 to 10 GHz. The attenuator exhibits a typical return loss of 17 dB from DC to 6 GHz and 15 dB from 6 to 10 GHz. Attenuation accuracy is within ± (0.4 + 4% of Atten. setting) dB up to 6 GHz and ± (0.5 + 5% of Atten. setting) dB up to 10 GHz.
This digital attenuator features a TTL/CMOS compatible dual-mode control interface, accepting either a three-wire serial input or a 4-bit parallel word. It is housed in a 24-lead 4x4mm QFN leadless surface mount package. The device is suitable for applications such as cellular infrastructure, WiBro/WiMAX/4G, microwave radio, VSAT, test equipment, and sensors.
