Description
This 7 x 7mm PAM is a 50Ω, quad-band dual mode, GSM/
EDGE PA module for 2.75G radio applications. In EDGE mode,
the module supports High/Low power mode feature to maximize
efficiency in low power operation. The module provides 50Ω
input and output terminals. The module also includes closed
loop power control circuitry for GSM applications, minimizing
the required external components and maximizing board yields.
