General Description
The HMC305LP4 & HMC305LP4E are broadband 5-bit positive control GaAs IC digital attenuators with CMOS compatible serial-to-parallel drivers packaged in leadless QFN 4 x 4 mm SMT packages. Covering 0.7 to 3.8 GHz, the insertion loss is typically less than 1.5 to 2 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 +3V to +5V applied through an external 5k Ohm resistor is required.
