Description
3.5 V WCDMA Handsets
The ECM010 is a power amplifier module at 3.5V Vcc with high efficiency. This device was developed using EiC鈥檚 own
InGaP Heterojunction Bipolar Transistor (HBT) process. It is optimized for WCDMA (digital) in the 1920 MHz to 1980 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. A proprietary temperature compensated bias circuit
provides nearly a constant Icq for low power mode from -40擄C to +85擄C. A Q control pin switches the quiescent current to
50mA for low output power range.
