Description

The HMC271LP4 & HMC271LP4E are broadband 5- bit positive control GaAs IC digital attenuators with serial-to-parallel drivers in low cost leadless QFN 4x4 mm SMT packages. Covering 0.7 to 3.7 GHz, the insertion loss of HMC271LP4 & HMC271LP4E  is typically less than 2.5 dB. The attenuator bit values are 1 (LSB), 2, 4, 8, and 16 dB for a total attenuation of 31 dB. Accuracy is excellent at ± 0.4 dB typical with an IIP3 of up to +48 dBm. Five bit CMOS compatible 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.
