Device
General Description
The RMPA0967 power amplifier module (PAM) is designed for
cellular band AMPS, CDMA, CDMA2000-1X, WCDMA and
HSDPA applications. The 2 stage PAM is internally matched to
50 Ohms to minimize the use of external components and fea-
tures a low-power mode to reduce standby current and DC
power consumption during peak phone usage. High power-
added efficiency and excellent linearity are achieved using Fair-
child RF’s InGaP Heterojunction Bipolar Transistor (HBT) pro-
cess.
