|ACPM-7833 CDMA1900 PCS Power Amplifier Module|
The ACPM-7833 is a fully matched CDMA Power amplifier module. Designed around Avago Technologies’ new Enhancement Mode pHEMT process, the ACPM-7833 offers premium performance in a very small form factor. Fully matched to 50 Ohms on the input and output.
The amplifier has excellent ACPR and efficiency performance at max Pout and low quiescent current with a single bias control voltage. For even lower quiescent current, a dynamic bias control circuit can be used by varying the voltage on the Vcntl pin between 1.2V to 2.5V.
Designed in a surface mount RF package, the ACPM7833 is cost and size competitive.
The ACPM-7833 is another key component of the Avago Technologies CDMAdvantage RF chipset.
