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 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 input and output matching networks.
Applications
• WCDMA handset (HSDPA)

Notes:
1. Electrical characteristics are specified under WCDMA modulated (3 GPP Uplink DPCCH + 1DPDCH ) signal unless specified otherwise.
2. Control current when series 6.2 kis used.
3. ACP is expressed as a ratio of total adjacent power to signal power, both with 3.84 MHz bandwidth at specified offsets.
4. TswhighDC, TswlowDC is time required to reach stable quiescent bias (10%) after Vcont is switched low and high, respectively.
TswhighRF, TswlowRF is time required to reach final output power (± 1 dB) after Vcont is switched low and high, respectively.
5. TonDC is time required to reach stable quiescent bias (10%) after Vref is switched high.
ToffDC is time required for the current to be less than 10% of the Iq after Vref is switched low.
6. TonRF is time required to reach final output power (±1 dB) after Vref is switched high.
ToffRF is time required to output power to drop 30 dB after Vref is switched low.

Notes:
1. Electrical characteristics are specified under HSDPA modulated Up-Link signal (DPCCH/DPDCH = 12/15, HS-DPCCH/DPDCH = 15/15).
2. ACP is expressed as a ratio of total adjacent power to signal power, both with 3.84 MHz bandwidth at specified offsets.
