Pin Assignment
The RDA6216 is a high-power, high-efficiency
quad-band power amplifier Module. This device is
designed for GSM850, EGSM900, DCS, PCS and
EDGE handheld digital cellular equipment. The
power amplifiers and their controller are fabricated
with GaAs Heterojunction Bipolar Transistor
(HBT) and CMOS respectively.The package of
this device is 6mm×6mm×1.1mm 10-pins LGA.
The input and output are realized on-chip matched
to 50Ω. The low-pass filter for ramping signal is
integrated in CMOS controller. The RDA6216
requires few external components, simplifying
PCB layout and reducing PCB board space.
