General Description
The HMC288MS8 & HMC288MS8E ꢁre broꢁdbꢁnd 0-
bit positive control GꢁAs IC digitꢁl ꢁttenuꢁtors in 8 leꢁd
MSOP surfꢁce mount plꢁstic pꢁckꢁges. Covering ±.7 to
0.7 GHz, the insertion loss is tꢀpicꢁllꢀ less thꢁn 1.2 to
1.8 dB. The ꢁttenuꢁtor bit vꢁlues ꢁre 2 (LSB), 4, ꢁnd 8
dB for ꢁ totꢁl ꢁttenuꢁtion of 14 dB. Accurꢁcꢀ is excel-
lent ꢁt ± ±.0 dB tꢀpicꢁl ꢂith ꢁn IIP0 of up to ꢃ+1 dBm.
Three bit control voltꢁge inputs, toggled betꢂeen ± ꢁnd
ꢃ0 to ꢃ+V, ꢁre used to select eꢁch ꢁttenuꢁtion stꢁte ꢁt
less thꢁn +± uA eꢁch. A single Vdd biꢁs of ꢃ0 to ꢃ+V
ꢁpplied through ꢁn externꢁl +K Ohm resistor is required
ꢂhile occupꢀing less thꢁn 14.8 mmꢄ.

Application Circuit
DC blocking cꢁpꢁcitors C1 & C2 ꢁre required on RF1 & RF2. Choose C1 = C2 = 1±± ~ 0±± pF to ꢁlloꢂ loꢂest customer specific
frequencꢀ to pꢁss ꢂith minimꢁl loss. R1 = +K Ohm is required to supplꢀ voltꢁge to the circuit throught either PIN + or PIN 8.

The circuit boꢁrd used in the finꢁl ꢁpplicꢁtion should
use RF circuit design techniques. Signꢁl lines
should hꢁve +± ohm impedꢁnce ꢂhile the pꢁck-
ꢁge ground leꢁds should be connected directlꢀ to
the ground plꢁne similꢁr to thꢁt shoꢂn. A sufficient
