Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The HMC305SLP4E is a broadband 5-bit forward-controlled silicon-based digital attenuator packaged in a CMOS-compatible serial-to-parallel driver configuration, featuring a leadless QFN 4x4 mm SMT package. The attenuator covers a frequency range from 0.4 to 6 GHz, with typical insertion loss of less than 1.6 dB. The attenuator's bit values are 0.5 dB (LSB), 1 dB, 2 dB, 4 dB, and 8 dB, with a total attenuation of 15.5 dB. The attenuator offers excellent attenuation accuracy, with a typical value of ±0.25 dB, and a third-order intercept point (IIP3) of up to +52 dBm. Each attenuation state is selected via a 5-bit serial control word. Requires a single Vcc bias voltage of +3.3V to +5V.
