LDMOS 2-stage integrated Doherty MMIC
The BLM9D2527-20AB is a 2-stage fully integrated Doherty MMIC solution using Ampleon's state of the art GEN9 LDMOS technology. The carrier and peaking device, input splitter and output combiner are integrated in a single package. This multiband device is perfectly suited as a final device in massive MIMO or small cell applications in the frequency range from 2500 MHz to 2700 MHz. Available in PQFN outline.
Features and benefits
- Integrated input splitter
- Integrated output combiner
- Very high efficiency thanks to asymmetry
- Designed for broadband operation (frequency 2500 MHz to 2700 MHz)
- Independent control of carrier and peaking bias
- Integrated ESD protection
- Excellent thermal stability
- Source impedance 50 Ω; high power gain
- Compliant to Directive 2002/95/EC, regarding restriction of hazardous substances (RoHS)
Applications
- RF power MMIC for multi-carrier and multi-standard GSM, W-CDMA and LTE base stations in the 2500 MHz to 2700 MHz frequency range.
