RICHARDSON RFPD Wolfspeed CMPA5259050S and CMPA5259080S are 50W and 80W respectively, 5.0–5.9GHz GaN MMIC power amplifiers that feature a two-stage reactively matched amplifier design approach that enables high power and power added efficiency to be achieved in a 5mm x 5mm surface mount (QFN) package. Devices are suitable for civil and military pulsed radar amplifier applications, including phased array radar. Additional key features include:

  • Typical power added efficiency
    • CMPA5259050S: >48%
    • CMPA5259080S: >50%
  • Small signal gain
    • CMPA5259050S: 29 dB
    • CMPA5259080S: 27 dB
  • Typical PSAT
    • CMPA5259050S: 110 W
    • CMPA5259080S: 65 W
  • Operation:
    • CMPA5259050S: up to 40 V
    • CMPA5259080S: up to 28 V
  • High breakdown voltage
  • High temperature operation
