ALM-11236

1710 MHz – 1850 MHz

Low Noise, High Linearity Amplier Module

with Fail-Safe Bypass Feature

Data Sheet

Description

Avago Technologies’ ALM-11236 is an easy-to-use GaAs

MMIC Tower Mount Amplier (TMA) LNA Module with low

IL bypass path. The module has low noise and high linearity

achieved through the use of Avago Technologies’ propri-

etary 0.25 mm GaAs Enhancement-mode pHEMT process.

All matching components are fully integrated within the

module and the 50 ohm RF input and output pins are

already internally AC-coupled. This makes the ALM-11236

extremely easy to use as the only external parts are DC

supply bypass capacitors. For optimum performance

at other bands, ALM-11036 (776-870 MHz), ALM-11136

(870-915 MHz) and ALM-11336 (1850-1980) are recom-

mended. All ALM-11x36 share the same package and pin

out conguration.
