ECM051
4 X 4 mm Dual Mode Cellular Band CDMA
3.5V POWER AMPLIFIER MODULE
Description
The ECM051 is a 10 signal pin 4 X 4 mm dual mode power
amplifier module at 3.5V Vcc with high efficiency. This
device was developed using EiC鈥檚 proprietary InGaP Gal-
lium Arsenide Heterojunction Bipolar Transistor (HBT) pro-
cess. It is optimized for cellular CDMA (digital) and AMPS
(analog) in the 824 MHz to 849 MHz band. It operates
from a positive voltage (3.2 - 4.2V Vcc) and includes a
power-down feature. The input and output are both matched
to 50鈩?internally. It is housed in a 4 X 4 mm Land Grid
Array package with 10 signal pins. A Q control pin switches
the quiescent current to 50mA for low output power range.
