Avago 公司的ACPM-7355是UMTS Band2 和Band5 頻段的雙頻段功率放大器模塊. ACPM-7355采用第5代CoolPAM電路技術,并采用先進InGaP HBTMMIC技術制造. ACPM-7355具有極好的線性,有三種功率控制模式:旁路/中功率模式/大功率模式,RF輸入和輸出內部50歐姆匹配阻抗.本文介紹了ACPM-7355主要特性, 方框圖, 在手機PCB應用電路和布局圖以及評估板電路圖與布局圖.
The ACPM-7355 is a dual-band PAM (Power Amplifier Module) designed for UMTS Band2 and Band5. The ACPM-7355 meets stringent UMTS linearity requirements.
The 4mmx5mm form factor 14-pin surface mount package is self contained, incorporating 50ohm input and output matching networks.
The ACPM-7355 features 5th generation of CoolPAM circuit technology which supports 3 modes – bypass, mid and high power modes. The CoolPAM is stage bypass technology which enables power amplifier to lower power consumption. Active bypass feature is added to 5th generation to enhance power added efficiency at low output range and this technology extends talk time of mobiles more by further saving power amplifier’s current consumption.
The power amplifier is manufactured on an advanced InGaP HBT (hetero-junction Bipolar Transistor) MMIC (microwave monolithic integrated circuit) technology offering state-of-the-art reliability, temperature stability and ruggedness.
The Module is housed in a cost effective, small and thin 4x5mm package.
ACPM-7355主要特性:
Dual-Band PA (Band2 and Band5)
Small Size (4x5mm)
Thin Package (0.9mm typ)
