Product Description
www.DataSheet.net/
The RF3283 is a high-power, high-efficiency transmit module containing RFMD’s
PowerStar™ integrated power control, integrated pHEMT front end antenna switch
and harmonic filtering functionality. All of which combine to provide for best in class
harmonic emission control and RX and TX insertion loss. The device is self-con-
tained with 50Ω input and output terminals with no matching components required.
The integrated power control function based on RFMD’s patented PowerStar™ con-
trol is incorporated, eliminating the need for directional couplers, detector diodes,
power control ASIC’s, and other power control circuitry; this allows the module to be
driven directly from the DAC output. The device is designed for use as the final por-
tion of the transmit chain in dual-band applications utilizing GSM900/DCS1800 and
eliminates the need for PA to antenna switch module matching. On-board power con-
trol provides over 70dB control range. The integrated antenna switch allows true
dual-band TX and RX functionality.

By regulating the power, the stages are held in saturation across all power levels. As the required output power is decreased
from full power down to -15dBm, the collector voltage is also decreased. This regulation of output power is demonstrated in
Equation 1 where the relationship between collector voltage and output power is shown. Although load impedance affects out-
put power, supply fluctuations are the dominate mode of power variations. With the RF3283 regulating, there are several key
factors to consider in the implementation of a transmitter solution for a mobile phone. Some of them are:
PdBm
=
10 ⋅ log
-(--2----⋅---V----C----C----–-----V----S---A---T---)--2-
8 ⋅ RLOAD ⋅ 10–3
(Eq. 1)
• Effective efficiency (ηEFF)
• Current draw and system efficiency
• Power variation due to Supply Voltage
• Power variation due to frequency
• Power variation due to temperature
• Input impedance variation
• Noise power
• Loop stability
• Loop bandwidth variations across power levels
• Burst timing and transient spectrum trade offs
• Harmonics
• Post PA loss
• Insertion loss in receive ports
• TX power leakage into the RX ports
• Performance during VSWR
• Time needed to implement the solution
• Needed board area for the solution
