Introduction

GDM3528 is a three-stage HBT general purpose power amplifier working at 3300~3600000 (Band 42, n78) with on-chip PA enable controller and temperature compensation circuits. This high efficiency and DPD-friendly PA can deliver up to 28dBm average output power and 37dBm peak power using 20MHz LTE signal (9.5dB PAR @ 0.01% CCDF). The product input and output are both internally matched to 50Ohm.

Features

• 3300MHz – 3600MHz
• 31dB Gain
• 25% PAE at 28dBm output power
• Typical -35dBc ACPR at 28dBm output power
• Higher than 37dBm peak power
• Wide instantaneous BW DPD friendly design
• Input/output internally matched to 50Ohm
• On-chip PA enable controller and temperature compensation circuits
• Compact and low-cost 5mm x 5mm LGA package (MSL3, 260°C per JEDEC J-STD-020)
• ESD Level: HBM 1000V; CDM 1000V

Applications
