WS2512-TR1G
4 x 4 Power Amplifier Module
for UMTS2100 (1920-1980 MHz)
Data Sheet
Description
Features
The WS2512-TR1G, 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
operates in the 1920-1980 MHz bandwidth.The WS2512-
TR1G meets the stringent WCDMA linearity requirements
for output power of up to 28 dBm.
A low current (Vcont) pin is provided for high efficiency
improvement of the low output power range.
• Excellent linearity
• Low quiescent current
• High efficiency
• 10-pin surface mounting package
4 mm x 4 mm x 1.1 mm (typ.)
• Internal 50 Ω matching networks for both RF input
and output
• RoHS compliant
The WS2512-TR1G features CoolPAM circuit technology
offering state-of-the-art reliability, temperature stability
and ruggedness. The WS2512-TR1G is self contained, in-
corporating 50 Ω input and output matching networks.
Applications
• WCDMA handset (HSDPA)
