Manufacturer: Analog Devices

Overview: Attenuators - DIGITAL - SMT OBSOLETE HMC305ALP4 / 305ALP4E v02.0311 0.5 dB LSB GaAs MMIC 5-BIT SERIAL CONTROL DIGITAL ATTENUATOR, 0.7 - 3.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The HMC305ALP4(E) is a broadband 5-bit positive control GaAs IC digital attenuator with CMOS patible serial-to-parallel driver package in a leadless QFN 4x4 mm SMT package.

Covering 0.7 to 3.8 GHz, the insertion loss is typically less than 1.5 to 2 dB.

The attenuator bit values are 0.5 (LSB), 1, 2, 4, and 8 dB for a total attenuation of 15.5 dB.

Key Features

  • The HMC305ALP4(E) is ideal for:.
  • Cellular/3G Infrastructure.
  • Fixed Wireless, WiMax & WiBro.
  • Test Instrumentation 0.5 dB LSB Steps to 15.5 dB CMOS Compatible Serial Data Interface SPI Compatible Serial Output ±0.3 dB Typical Bit Error 24 Lead 4x4mm QFN Package: 16mm² Included in the HMC-DK004 Designer’s Kit Functional Diagram General.
