The appeal of quickly deploying POT’s (Plain Old Telephones) in vast regions of the world with little existing "copper" infrastructure remains a prime motivator in the development of Wireless Local Loop systems. Compound this demand with the need for data transmission and internet access leads one to the conclusion that projected growth for WLL is likely to occur. AML products and ongoing R&D actively supports industry requirements for transmit and receive amplifiers that provide solutions for TDMA and W-CDMA WLL systems. AML Designs provide the efficiency, reliability and linearity associated with GaAs devices enhanced by AML’s predistortion technology supported by an embedded digital signal processing microprocessor. Full status and performance monitoring information is provided on discrete signal lines at the interface connector. Built in DC to DC converters permit operation from wide range DC input voltage.

AML Two-Way Messaging tower top receive amplifiers provide the ultimate uplink sensitivity improvement. By using a combination cavity filter and low noise amplifier to set the system noise floor prior to the loss of the receive antenna to base station feed cable this product greatly enhances signal to noise ratio. A rack mounted smart controller injects the DC supply onto the antenna feed and monitors the tower top low noise amplifier operating conditions. AML also provides low noise, high dynamic range receive multicouplers suitable for mounting in the base station equipment racks. These products represent the highest levels of industry performance. AML power amplifiers address two-way messaging down-link requirements. Key on the RMPA-1 tab for more information on this representative product.

AML receiving multicouplers are built upon the extensive bedrock of in-hose intercept and passive component knowledge accumulated over years of R&D effort. Key elements of multicoupler excellence include a maximum of isolation between outputs with a minimum of contributed intermodulation products and low noise. Products are available for all applications from 32MHz to 3.5GHz. These bands include the popular cellular, messaging, public safety and the P, L & S band telemetry bands. Multicouplers are frequently designed to custom specifications, we want your business!
