HMC603QS16 0.5dB LSB 5-Bit Digital Attenuator SMT, 0.7 - 3.8 GHz
The HMC603QS16(E) is a general purpose broadband 5-bit positive control GaAs IC digital attenuator in a 16 lead QSOP surface mount plastic package. Covering 0.7 to 3.8 GHz, the insertion loss is less than 1.9 dB typical. 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 ± 0.15 dB typical with an IIP3 of +50 dBm. Five bit control voltage inputs, toggled between 0 and +3 to +5V, are used to select each attenuation state at less than 1 uA each. A single Vdd bias of +3 to +5V applied through an external 5K Ohm resistor is required.
