TQM 7M4014
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 – 849 MHz, 880 – 915 MHz, 1710 – 1785 MHz, and
1850 – 1910 MHz bands. Module construction is a low-profile
overmolded land-grid array on laminate.
