Functional Diagram

General Description

The HMC603QS16 & HMC603QS16E are general

purpose broadband 5-bit positive control GaAs IC

digital attenuators in 16 lead QSOP surface mount

plastic packages. Covering 0.7 to 3.8 GHz, the inser-

tion 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 excel-

lent 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.

T_A= +25° C, Vdd= +3V to +5V & Vctl= 0/Vdd (Unless Otherwise Stated)
