Bilateral Amplifiers 

The AAA series of Bilateral Amplifiers are designed to improve the range of 902-928 MHz spread spectrum transceivers by amplifying both the transmitted and received signals right at the antenna, mitigating cable loss. On the receive side the amplifier incorporates GaAs FET amplification along with SAW and dielectric resonator filtering. This achieves a 1.5 dB Noise Figure and a +5 dBm input intercept point along with 40 dB of cellular and pager band rejection. A combination of SAW and low-pass filtering reduces harmonic output to less than -70 dBc. 

The amplifiers require 12 VDC and are powered through the antenna cable, simplifying the installation process. The product is packaged in sealed milled aluminum housing, providing the utmost in weather protection. 

Available in 1 Watt and 5 Watt (for military customers only) models, the AAA series of amplifiers are the ideal solution for extending the range of spread spectrum radios. 

The Bilateral Amplifiers are for use only by US Government or Military customers or for export.
