Product Overview
BLM7G1822S-80PBG is a 2-stage LDMOS MMIC power amplifier from Ampleon, working at 1805–2170MHz with 80W P3dB output. It integrates driver and power stages, on-chip matching, ESD protection and temperature-compensated bias, simplifying PCB layout. Designed for cellular base stations, it supports various PA topologies with reliable linearity and thermal stability.
Core Advantages
Integrated Two-Stage Architecture
Driver and power stages are integrated in one chip, with 28dB typical gain, reducing cascaded amplifiers and PCB size.
Wide Frequency Adaptation
Covers DCS, PCS and UMTS bands, suitable for macro, micro and small cell base stations.
On-Chip Matching & Protection
Built-in 50Ω matching, ESD protection and temperature-stable bias enhance device reliability.
Dual Independent Channels
Dual amplifier paths support single-ended, push-pull and Doherty designs for flexible circuit arrangement.
High Thermal Stability
Low static current drift guarantees stable performance in wide temperature environments.
