WS1403
CDMA PCS 3x3 Power Amplifier Module
(1850-1910 MHz)
Data Sheet
Description
The WS1403 is a CDMA Personal Communication Service
(PCS) Power Amplifier (PA), designed for handsets
operating in the 1850~1910 MHz bandwidth.
Digital mode control of CoolPAM reduces current
consumption, which enables extended talk time of
mobile devices.
The WS1403 meets stringent CDMA linearity
requirements to and beyond 28 dBm output power. The
3 mm x 3 mm form factor 8-pin surface mount package
is self contained, incorporating 50 ohm input and output
matching networks.
Features
  Excellent linearity
  Low quiescent current
  High efficiency
  PAE at 28 dBm: 39.8%
  PAE at 17 dBm: 22.3%
  8-pin surface mounting package
  3 mm x 3 mm x 1.0 mm
  Internal 50 ohm matching networks for both RF input
and output
  RoHS compliant
Applications
  Digital CDMA PCS
  Wireless Local loop

Notes:
• Recommended voltage for Vref is 2.85 V.
• Place C1 near to Vref pin.
• Place C3 and C4 close to pin 4 (Vcc1) and pin 5 (Vcc2). These capacitors can affect the RF performance.
• Use 50 W transmission line between PAM and Duplexer and make it as short as possible to reduce conduction loss.
• π-type circuit topology is good to use for matching circuit between PA and Duplexer.
Calibration
Calibration procedure is shown in Figure 11. Two
calibration tables, high mode and low mode respectively,
are required for Cool PAM, which is due to gain difference
in each mode. For continuous output power at the mode
change points, the input power should be adjusted
according to gain step during the mode change.
TX_AGC
Offset Value (Difference between Rising Point and Falling
Point)
Offset value, which is the difference between the rising
point (output power where PA mode changes from low
mode to high mode) and falling point (output power
where PA mode changes from high mode to low mode),
should be adopted to prevent system oscillation. 3 to 5
dB is recommended for hysteresis.
