ACPM-7381-TR1
UMTS200 4x4 Power Amplifier
(920-980MHz)
Data Sheet
Description
The ACPM-7381, a Wide-band Code Division Multiple
Access(WCDMA) Power Amplifier (PA), is a fully matched
10-pin surface mount module developed for WCDMA
handset applications. This power amplifier module is
developed to cover 1920-1980MHz bandwidth. The
ACPM-7381 meets the stringent WCDMA linearity require-
ments for output power of up to 28dBm. The ACPM-7381
is also developed to meet HSDPA specs.
The ACPM-7381 is designed to enhance the efficiency at
low and medium output power range by using 3-mode
control scheme with 2 mode control pins. This provides
extended talk time.
The ACPM-7381 is self contained, incorporating 50ohm
input and output matching networks.
