3V Quad-Band GSM850/GSM900/DCS/PCS Power Amplifier Module

Package Outline:

Description:

Advanced quad-band, compact 3V power amplifier module

designed for mobile handset applications. The small size and

high performance is achieved with high-reliability InGaP HBT

technology. The module is fully integrated, providing a simple

50 Ohms interface on all input and output ports. It includes

internal closed-loop power control. No external matching or

bias components are required. Despite its very compact size,

the module has exceptional efficiency in all bands.

Description:

The module incorporates two highly-integrated InGaP power

amplifier die with a CMOS controller. Each amplifier has three

gain stages with on-die interstage matching implemented with

a high Q passives technology for optimal performance. The

CMOS controller implements a fully integrated closed-loop

power control within the module. This eliminates the need for

any external couplers, power detectors, current sensing etc.,

to assure the output power level. The latter is set directly from

the V

ramp

input from the DAC. The module has Tx enable and

band select inputs. Excellent performance is achieved across

the 824 鈥?849 MHz, 880 鈥?915 MHz, 1710 鈥?1785 MHz, and

1850 鈥?1910 MHz bands. Module construction is a low-profile

overmolded land-grid array on laminate.
