ALM-38140 - 50MHz - 4GHz PIN Diode Variable Attenuator

General Description

Avago Technologies’ ALM-38140 is a fully matched wideband variable attenuator module with high linearity performance and high dynamic range.

The high dynamic range and low phase shift can be achieved with only one external inductor place between Linput and Loutput.

Key Features

  • Fully integrated module.
  • High dynamic range.
  • Excellent Input IP3 performance.
  • High Input P1dB compression.
  • Low phase shift performance.
  • Tape-and-Reel packaging option available Specifications Typical Performance at 1.9GHz.
  • Attenuation : 39dB.
  • Insertion Loss : 3.2dB.
  • Input IP3 : 50dBm.
  • Input P1dB : > 30dBm Package Marking Vcontrol Loutput Linput.

ALM-38140 www.DataSheet4U.com 50MHz – 4GHz PIN Diode Variable Attenuator Module Data Sheet Description Avago Technologies’ ALM-38140 is a fully matched wideband variable attenuator module with high linearity performance and high dynamic range. The high dynamic range and low phase shift can be achieved with only one external inductor place between Linput and Loutput. ALM-38140 is a fully integrated solution using Avago Technologies’ low distortion silicon PIN diodes housed in a miniature 3.8 x 3.8 x 1.0 mm3 MCOB (Multiple-Chips-OnBoard) package. This variable attenuator module is easily operated with a constant voltage, Vsupply = 2.7V and a control voltage, Vcontrol = 1 – 5V. No external biasing components needed. ALM-38140 is ideal for gain control in RF amplifier circuits.
