SKY77344-21 - Power Amplifier Module

Description

When the SKY77344-21 PAM saturates under conditions of low battery and/or VSWR, a decrease in the internal power control loop gainbandwidth occurs, producing high level switching transients on the falling edge of the burst.

Features

  • er reduction target is met, at which point.

APPLICATION NOTE SKY77344-21 Power Amplifier Module — Evaluation Information Applicability: SKY77344 Version -21 Introduction This Application Note describes the functionality, board layout and applications instructions of the SKY77344-21 Power Amplifier Module. The SKY77344-21 Power Amplifier Module (PAM) is designed for quad-band cellular handsets comprising GSM850/900, DCS1800/ PCS1900, and supports Class 12 General Packet Radio Service (GPRS) multi-slot operation, and Enhanced Data GSM Environment (EDGE) (8PSK) linear modulation. A single analog control voltage is used at the VRAMP port for both GMSK and EDGE modes. The active logic level at the MODE terminal determines the function of the VRAMP signal.
