Download Datasheet (PDF)

The EMTS Telecom Services Power Amplifier, model MCPA-750-48W50 is designed for single and multi-channel LTE, and 5G applications in the band-12, 13, 14; This amplifier utilizes linear LDMOS power devices that provide high gain, wide dynamic range, low distortions, and excellent group delay and phase linearity. Exceptional performance, long-term reliability, its high efficiency are achieved by employing APD (Analog Pre-distortion) technology, advanced matching networks, and combining techniques (Doherty Design), EMI/RFI filters, machined housings, and qualified components. EMTS Cellular Power Amplifiers are ideal for customers involved with DAS systems, BTS solutions, and RF repeaters, requiring highly linear products with low distortion and EVM. EMTS's high-quality design makes the MCPA extremely stable within an overall environmental temperature range
