Designed with broadband input and output match, Avago’s ALM-38140 does not require any external RF matching component to operate. Additionally, narrow band performance enhancement can be easily achieved by applying a single external inductor. The ALM-38140 also features high power handling capabilities (P1dB>30dBm @ 1,900 MHz), great linearity performance (IIP3: 60 dBm @ 1,900 MHz) and superior dynamic range (35 dB @ 1,900 MHz). With broadband coverage, this miniature variable attenuator module is ideal for use in automatic gain control (AGC) and temperature compensation circuitry applications which operate within the 50 – 4,000 MHz frequency range.
Avago Launches Fully Integrated Broadband Miniature Variable Attenuator Module for Wireless Infrastructure Applications
Avago has announced a new fully matched wideband variable attenuator module for use in a wide range of broadband system applications. The ALM-38140, which is a 50MHz to 4 GHz PIN diode attenuator module, is a fully integrated solution that uses Avago’s low distortion silicon PIN diodes housed in a miniature 3.8 mm by 3.8 mm by 1.0 mm multiple-chip-on board (MCOB) package with 6-pin configuration pads. This module is ideal for use wireless infrastructure applications such as CATV, WCDMA, VSAT, WiMAX and cellular base station applications.
