BENEFITS TO YOU
Reduced cost with higher level integration of upmixer and exciter RF AGC
amplifier functions.
Greatly simplifies achieving CDMA transmitter specifications by having RF
AGC in the exciter amplifier.
Simplified design of dual-band/ dual-mode cellular phones with upmixer/
exciter amplifier ICs specifically designed for CDMA frequencies.
Reduces linearity requirement for power amplifier due to very low
cascaded adjacent channel power.
Improved efficiency of entire RF transmit chain with excellent cascaded
adjacent channel power specification.
Can drive power amplifier directly, without an additional amplifier
stage, due to excellent output power and third order intercept point of
exciter amplifier.
Lowers system cost and manufacturing costs due to integrated, on-chip
linear gain control and selectable bias control circuitry.
Can be used in three-cell battery-powered applications with a power supply
voltage as low as 2.7 V.
Provides higher circuit and system density with the new high power
TSSOP-20EP surface mount package.
Smaller battery for portable applications with 2.7 V operation and selectable
bias to reduce power consumption.
Improved reliability due to lower power dissipation.
A SOLUTION FOR THESE QUESTIONS
Do you need to design a dual-band/ dual-mode CDMA cellular phone
using upmixers and exciter amplifiers with RF AGC specifically
designed for CDMA frequencies
Do you want to reduce the parts count and lower your manufacturing costs
by using an integrated upmixer and RF AGC (exciter) amplifier
Do you need to reduce the linearity requirement for your power amplifier,
and improve the efficiency of the entire RF transmit chain
Would you like to eliminate an additional amplifier stage by driving the
power amplifier directly with the exciter amplifier
Does your design require that the battery size be reduced with a supply
voltage as low as 2.7 V and low power consumption
Do you want to reduce the parts count and lower your manufacturing costs
with on-chip linear gain control and selectable bias control circuitry
Do you want to reduce the pc board area for your CDMA cellular phone
