LTE Band 28 MIPI APT Power Amplifier

Currently Viewing:

The Broadcom ACPM-9328 is a fully matched 10-pin surface mount power amplifier (PA) module developed for LTE Band 17 and Band 12. The 2mm×2.5mm form factor package is self contained, incorporating 50-ohm input and output matching networks. 
The ACPM-9328 features the CoolPAM circuit technology that supports two power modes - low and high. A directional coupler is integrated into the module, and both coupling and isolation ports are available externally, which support a daisy chain. The integrated coupler has excellent coupler directivity, which minimizes the coupled output power variation or delivered power variation caused by a load mismatch from the antenna.
