B71 617MHz 50 Watts Multi Carrier Solid State Power Amplifier
The EMTS Telecom Services Power Amplifier, model MCPA-617-48W50 is designed for single and multi-channel WCDMA, LTE, and 5G applications in the band 71 and is also suitable for GSM. 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 and 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 systems, which require highly linear products with low distortion and low EVM.
