The HMC540LP3 & HMC540LP3E are broadband
4-bit GaAs IC digital attenuators in low cost leadless
surface mount packages. This single positive control
line per bit digital attenuator utilizes off chip AC
ground capacitors for near DC operation, making it
suitable for a wide variety of RF and IF applications.
Covering DC to 5.5 GHz, the insertion loss is less
than 1 dB typical. The attenuator bit values are
1 (LSB), 2, 4 and 8 dB for a total attenuation of 15 dB.
Attenuation accuracy is excellent at ?0.2 dB typical
step error. The attenuator also features a IIP3 of +50
dBm. Four TTL/CMOS control inputs are used to
select each attenuation state. A single Vdd bias of
+5V is required.
