Transmission and reception IC for cellular telephone
■ Overview
The AN6096FHN is a transmission and reception IC for a cellular telephone. It is encapsulated in
the QFN package which is very thin and very small
outline by using our exclusive process method.
It integrates QPSK (Quadrature phase shift keying) modulator for transmission and an IF circuit
for reception in a single chip. It contributes to realization of thinner and lighter equipment by adopt-

ing a very small package and designing a low power
consumption circuit.
R0.3
■ Features
• Integrating an orthogonal modulation circuit for
transmission and an IF circuit for reception on a
single chip
• Low power consumption by using an indirect
modulation system in transmission block
• Built-in APC circuit for transmission output adjustment
• High input sensitivity by optimizing circuit in reception circuit
• Built-in RSSI circuit of wide dynamic range in reception block
■ Applications
• Cellular telephone
