The EMTS Telecom Services Power-Amplifier is designed for multi-channel LTE applications. This amplifier utilizes linear LDMOS power devices that provide high gain, wide dynamic range, low distortions, excellent group delay and phase linearity. Exceptional performance, long-term reliability, and high efficiency are achieved using APD (Analog Pre-Distortion) technology, advanced matching networks, and combining techniques (Doherty Design). The MCPA supports TDD modulation, and includes Uplink and Downlink paths. EMI/RFI filters, machined housings, and qualified components. EMTS Cellular Power Amplifiers are ideal for customers with DAS systems, BTS solutions, and RF repeaters. The MCPA utilized the linearization technique to provide excellent efficiency, and linearity characteristics offer low distortion and EVM. EMTS's high-quality design makes our MCPA extremely stable within an overall environmental temperature range. We offer multiple types for all LTE standard bands.

interference and oscillation problems, challenging coverage holes, rapid response deployment, and inadequate in-building coverage. Regardless of the technology or frequency, EMTS can provide customized coverage solutions that address any combination of unique and complex network needs for Wireless Networks.
