DATA SHEET • SKY77500
IPAC™ FEM FOR QUAD-BAND GSM / GPRS
Electrical Specifications
This section contains the following tables for the electrical
characteristics of the SKY77500 Power Amplifier Module.
The absolute maximum ratings and recommended operating
conditions for the SKY77500 are listed in
Table 1
and
Table 2,
respectively.
Table 3
specifies the mode control logic and
Table 4
contains the electrical characteristics of the SKY77500 for the
modes, GSM850, GSM900, DCS1800, and PCS1900.
Figure 2
is a
diagram of a typical SKY77500 application.
The SKY77500 is a static-sensitive electronic device and should
not be stored or operated near strong electrostatic fields. Detailed
information on device dimensions, pin descriptions, packaging
and handling can be found in later sections of this data sheet.
