ACPM-500x/520x: UMTS/CDMA/LTE PAMs (Power Amplifier Modules)

Sponsored Content

The ACPM-500x PAMs (Power Amplifier Modules) are designed to meet the requirements of MultiMode applications including UMTS (universal mobile telecommunication system), CDMA (code division multiple access) and LTE (long term evolution).

The ACPM-520x PAMs are optimized to maximize the PAE at maximum RF powers by adjusting maximum output powers. These modules are intended to meet UMTS specifications. With multiple product lines, customers have the flexibility to choose the right products for their application.

All of the PAMs benefit from Avago's fifth generation CoolPAM technology that lowers quiescent current to 3.0 mA typically and adds a switchless active bypass mode for higher PAE at low output power levels. High efficiency at low power output has become an important design parameter for handset manufacturers since in urban and suburban areas with good cellular coverage handsets usually transmit at low power. The PAMs feature PAE of 12-20% of maximum output power in bypass mode and 20-25% of maximum output power in mid-power mode, representing improvements over existing power amplifiers in the market. CoolPAM technology enables mobile handset designers to extend the usage time without an increase of battery capacity. All ACPM 500x and ACPM-520x UMTS power amplifiers include a 20 dB directional coupler. The high directivity makes precise power control possible. For multi-band handsets, the internal directional coupling and isolation ports are available for daisy chaining. This simplifies system printed circuit board (PCB) layout.

The power amplifiers are manufactured on advanced InGaP HBT (hetero-junction Bipolar Transistor) MMIC (microwave monolithic integrated circuit) technology with proven state-of-the-art reliability, temperature stability and ruggedness.
