MAX2266 Power Amplifier for the CDMA Cellular Band with PIN Diode Switch

Abstract: A complete application circuit for the MAX2266 cellular band CDMA power amplifier (PA) is introduced. Details of the PIN diode switch are provided, as well as output power, gain, ACPR, power-added efficiency (PAE) and idle supply current data for the circuit. The low-power mode (only 39mA idle current) offers 15-16% PAE at +15dBm output power, and 11% PAE at +13dBm.
