0.25-watt analog variable gain amplifier for cellular infrastructure applications

Avago technology has announced the addition of two miniature 0.25-Watt analog variable gain amplifiers for cellular infrastructure applications.

The ALM-80110/80210 features a common footprint for easy integration into most base station designs. The ALM-80110 operating frequency from 0.4 to 1.6 GHz, where the ALM-80210 operating frequency from 1.6 to 2.7 GHz, which are ideal for use in WLL, WLAN, transmitter receiver gain control, and temperature compensation circuitry applications.

The ALM-80110/80210 integrates high linearity 0.25W amplifiers and silicon PIN diode-based pie attenuator into a miniature multiple-chips-on-board (MCOB) module package and requires a minimum amount of external RF matching components, and are used in Avago's proprietary 0.25 um GaAs enhancement-mode pHEMPT process and low distortion silicon pin diode technologies.

Key features are,

Superior linearity and high dynamic range
High power handling capability
Wide gain control range
High OIP3 across attenuation range
Easy to use with broadband input fully matched and output pre-matched
Common footprint, external match network and PCB layout across 400 to 2700 MHz
Halogen free
Pb-Free and RoHS compliant

Package: compact 5 mm by 5 mm by 1.1 mm, 10-lead module package.
Price: Each $2.93 for 10k pieces
