RFMW announced design and sales support for two MMIC power amplifiers (PAs) fromCML Microcircuits. The CMX90A003 and CMX90A004 are two-stage, fully matched MMIC PAs for use in 860 to 960 MHz, license-free bands. Advanced GaAs HBT technology provides a combination of high efficiency (49 percent PAE) and gain (30 dB). The CMX90A003 is optimized for efficiency at low collector voltages (1.9 to 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 to 4.5 V and intended as a final stage amplifier with 32.5 dBm saturated output power.
