Functional Diagram
General Description
The HMC540SLP3E is a broadband 4-bit Silicon
IC digital attenuator in a low cost leadless surface
mount package. 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 0.1 to 8 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 +56dBm. Four TTL/CMOS control inputs are used
to select each attenuation state. It can operate with a
single Vdd ranging from +3.3V to 5V.
Electrical Specifications,
TA = +25° C, With Vdd = +5V & Vctl = 0/+5V (Unless Otherwise Noted)
