Typical Applications
The HMC305SLP4E is a broadband 5-bit positive
control Silicon IC digital attenuator with CMOS com-
patible serial-to-parallel driver package in a lead-
less QFN 4x4 mm SMT package. Covering 0.4 to 6
GHz, the insertion loss is typically less than 1.6 dB.
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 excellent at ±0.25 dB typical with an IIP3
of up to +52 dBm. Five bit serial control words are
used to select each attenuation state. A single Vcc
bias of +3.3V to +5V is required.
The HMC305SLP4E is ideal for both RF and IF
applications:
• Cellular Infrastructure
• Wireless Infrastructure
• Microwave Radio & VSAT
• Test Instrumentation
