0.5 dB LSB GaAs MMIC 5-BIT DIGITAL
POSITIVE CONTROL ATTENUATOR, 0.7 - 3.8 GHz
General Description
Features
Functional Diagram
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.
