HMC305S Glitch Free 0.5 dB 5-Bit Serial Control Silicon Digital Attenuator, 0.4 - 7.0 GHz

The HMC305SLP4E is a broadband 5-bit positive control Silicon IC digital attenuator with CMOS compatible serial-to-parallel driver package in a leadless QFN 4x4 mm SMT package. Covering 0.4 to 6 GHz, the insertion loss is typically less than 1.6 dB. The attenuator bit values are 0.5 (LSB), 1, 2, 4, and 8 dB for a total attenuation of 15.5 dB. Attenuation accuracy is excellent at ±0.25 dB typical with an IIP3 of up to +52 dBm. Five bit serial control words are used to select each attenuation state. A single Vcc bias of +3.3V to +5V is required.

The HMC305S(E) is a replacement for the HMC305A(E), HMC305B(E) and HMC305(E).
