AN6095SH
Reception IF
+ transmission quadrature modulation IC for PHS and
cellular telephone
I Overview
The AN6095SH is a single chip IC for PHS reception
IF block and transmission block.
Reception IF block is incorporating a 2nd down-mixer
and a limiter/RSSI circuit which can operate for up to
300 MHz of input frequency. Transmission block is in-
corporating a quadrature modulator, a phase shifter, an
up-mixer for 1.9 GHz and output level control functions.
It contributes to realization of small package and small
size of equipment.
I Features
Operating supply voltage range: 2.7 V to 4.0 V
Current consumption
Transmission block: 28 mA
Reception block: 5.3 mA
Sleep mode: 10
A or less
(Transmission block)
Output level: -8 dBm
Output frequency: up to 2 GHz
Transmission IF frequency: 100 MHz to 300 MHz
(Reception block)
RSSI input D range: 80 dB
Mixer conversion gain: 16 dB
Limiter voltage gain: 70 dB
2nd down-mixer NF: 6 dB
