| Agilent ACPM-7833 CDMA1900 (PCS) Power Amplifier Preliminary Data Sheet Features * Operating frequency: 1850 - 1910 MHz * 28.5 dBm linear output power @ 3.4 V * High efficiency: 40% PAE * Very low quiescent current with single control voltage or * Dynamic bias control Description The ACPM-7833 is a fully matched CDMA Power amplifier module. Designed around Agilent 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; Vcntl = 1.2V to 2.2V. Designed in a surface mount RF package, the ACPM-7833 is cost and size competitive. The ACPM-7833 is another key component of the Agilent CDMAdvantage RF chipset. * Internal 50 ohm matching networks for both RF IN/OUT * 3.2 - 4.2 V linear operation * cdma2000 1xRTT capable * Only 3 SMT parts needed * 4.0 x 4.0 x 1.1 mm SMT package Applications * CDMA handsets * Datacards * PDAs Vdd1 Vdd3 Vdd2 Bias Circuit Power Input Match On Chip Inter-stage Match Passive Output Match Input Output Vcntl Single control bias setting for low Idq and 40%PAE at Pout = 28.5 dBm Preliminary Product Disclaimer This preliminary data sheet is provided to assist you in evaluating this product that is under development.
