Device Overview

General Description

The AMM-11059CH is a wideband GaAs distributed amplifier covering 0.01 to 50 GHz, delivering 12 dB small-signal gain with high output power and linearity. It provides up to +27 dBm saturated output power, with output IP3 up to +35 dBm. Operating from a 12 V supply at 220 mA typical current, the amplifier is internally matched to 50 Ω at both the RF input and output ports. These features make it well-suited for wideband driver stages in RF/mmWave front ends, test and measurement instrumentation, electronic warfare, and general-purpose broadband gain block applications.

Specifications

Absolute Maximum Ratings

The Absolute Maximum Ratings indicate limits beyond which damage may occur to the device. If any one of these limits are exceeded, the device may become inoperable or have a reduced lifetime. Reliability limits are individual, instantaneous catastrophic limits only. Functional operation limits are indicated below. Operation of the device at multiple absolute maximum limits or for extended periods at a single limit can cause degradation and damage to the device.
