Features
General Description
40% WCDMA efficiency at +28 dBm Pout
The RMPA2263 Power Amplifier Module (PAM) is Fairchild’s
14% WCDMA efficiency (85 mA total current) at +16 dBm
Pout
Linear operation in low-power mode up to +19 dBm
Low quiescent current (Iccq): 25 mA in low-power mode
Meets UMTS/WCDMA performance requirements
latest innovation in 50 Ohm matched, surface mount modules
targeting UMTS/WCDMA/HSDPA applications. Answering the
call for ultra-low DC power consumption and extended battery
life in portable electronics, the RMPA2263 uses novel
proprietary circuitry to dramatically reduce amplifier current at
low to medium RF output power levels (< +16 dBm), where the

handset most often operates. A simple two-state Vmode control
Single positive-supply operation with low power and shut-
down modes
– 3.4V typical Vcc operation
– Low Vref (2.85V) compatible with advanced handset
chipsets
Compact Lead-free compliant LCC package –
(4.0 x 4.0 x 1.5 mm nominal)
is all that is needed to reduce operating current by more than
50% at 16 dBm output power, and quiescent current (Iccq) by
as much as 70% compared to traditional power-saving
methods. No additional circuitry, such as DC-to-DC converters,
are required to achieve this remarkable improvement in
amplifier efficiency. Further, the 4 x 4 x 1.5 mm LCC package is
pin-compatible and a drop-in replacement for last generation 4 x
4 mm PAMs widely used today, minimizing the design time to
