High-Power Low-Voltage GaAs HBT Amplifiers

The CML Microcircuits CMX90A003 two-stage, fully matched MMIC power amplifier for use in 860 – 960 MHz, license-free bands.

RFMW announces design and sales support for two MMIC power amplifiers from CML Microcircuits. The CMX90A003 and CMX90A004 are two-stage, fully matched MMIC power amplifiers for use in 860 – 960 MHz, license-free bands. Advanced GaAs HBT technology provides a combination of high efficiency (49% PAE) and gain (30 dB). The CMX90A003 is optimized for efficiency at low collector voltages (1.9 – 2.5 V) while delivering 29.5 dBm of saturated power, ideal as a booster PA for range extension of low-power transceivers, it’s suitable for systems with supercapacitor backup storage, thus extending the discharge period or battery life. The CMX90A004 is optimized for maximum efficiency at collector voltages of 2.7 – 4.5 V and intended as a final stage amplifier with 32.5 dBm saturated output power.
