CT2 Front End IC
Description
U7001BG is a monolithic GaAs transmit/ receive front
end with power amplifier, low noise amplifier and
antenna switch. It is specially designed for operation in
CT2 band and suitable for a frequency range of 839 MHz
to 952 MHz with external matching.
Electrostatic sensitive device.
Observe precautions for handling.
Features
D Low supply voltage 3.6 V typical (min. 2.7 V)
D High power added efficiency (typ. 40%)
D Low power consumption in receive mode
D Power down control pin for low noise amplifier
D Gain control of power amplifier
D Low noise amplifier
D Optional high output power 50 mW @ 5 V supply
voltage
Benefits
D Extended talk time due to low power consumption and
high PAE
D Few external components and very small package
save space
