DOHERTY AMPLIFIER FOR BASE STATIONS
We have the knowledge and experience of designing and building high efficient Doherty Power amplifiers for different frequency bands (700MHz up to 3GHz) and output powers (up to 1kW).
We take care of the complete realization (mechanical and electrical) of the demo board. The necessary mechanical parts can be created in-house. We are able to measure and characterize the Doherty amplifier in-house.
For one customer we made and still produce Doherty demo boards for many different types of devices.
The challenge is to create a physical compact design, in a short time frame, with the highest electrical efficiency and output power.
• Frequency band : 758 – 803 MHz
• Saturated power : 58.5 dBm (700W)
• Instantaneous Efficiency: 60% @ 8 dB back-off
• Power gain: 18 dB
• High video bandwidth
• Ninth generation High Voltage (50V) Ampleon LDMOS
• Two way inverted asymmetrical (IADPA)
• Rogers RO3006 25 mil, 35 µm copper
• ADS + Momentum tooling
