The B10G3438N55D is a 3-stage fully integrated asymmetrical Doherty MMIC solution using Ampleon’s state of the art GEN10 LDMOS technology. The carrier and peaking device, input splitter, output combiner and pre-match are integrated in a single package. This multiband device is perfectly suited as a final stage for small cells and massive MIMO applications in the frequency range from 3400 MHz to 3800 MHz. Available in PQFN outline.
Features and benefits
- Integrated input splitter
- Integrated output combiner
- 30 Ω output impedance thanks to integrated pre-match
- Very high efficiency thanks to asymmetry
- Designed for wideband operation (frequency 3400 MHz to 3800 MHz)
- Independent control of carrier and peaking bias
- Integrated ESD protection
- Source impedance 50 Ω; high power gain
- For RoHS compliance see the product details on the Ampleon website
