Description

The HMC271LP4 & HMC271LP4E are broadband 5-bit positive control GaAs IC digital attenuators with CMOS compatible serial-to-parallel drivers in low cost leadless QFN 4x4 mm SMT packages. Covering 0.7 to 3.7 GHz, the insertion loss is typically less than 2.5 dB. The 271LP4E 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.
