PRELIMINARY DATA SHEET
ECM001
Dual Mode Cellular CDMA/AMPS
3.5V POWER AMPLIFIER MODULE
Description
The ECM001 is a dual mode power amplifier module at
3.5V Vcc with high efficiency. This device was developed
using EiC鈥檚 own InGaP Gallium Arsenide Heterojunction
Bipolar Transistor (HBT) process. 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 - 4V
Vcc) and includes a power-down feature. The input and
output are both matched to 50鈩? It is housed in a 6 X 6
mm Land Grid Array package.
