Download datasheetLDMOS 2-stage power MMIC
The BLM7G1822S-40AB(G) is a dual section, asymmetric, 2-stage power MMIC using Ampleon’s state of the art GEN7 LDMOS technology. This multiband device is perfectly suited as small cell final in Doherty configuration, or as general purpose driver in the 1805 MHz to 2170 MHz frequency range. Available in gull wing or straight lead outline.
Features and benefits
- Designed for broadband operation (frequency 1805 MHz to 2170 MHz)
- High section-to-section isolation enabling multiple combinations
- High Doherty efficiency thanks to 2 : 1 asymmetry
- Integrated temperature compensated bias
- Biasing of individual stages is externally accessible
- Integrated ESD protection
- Excellent thermal stability
- High power gain
- On-chip matching for ease of use
- Compliant to Directive 2002/95/EC, regarding restriction of hazardous substances (RoHS)
Applications
-
RF power MMIC for W-CDMA base stations in the 1805 MHz to 2170 MHz frequency range. Possible
circuit topologies are the following:
- Asymmetric final stage in Doherty configuration
- Asymmetric driver for high power Doherty amplifier
