DESCRIPTION
The μPC8126GR is a silicon monilithic integrated circuit designed as 900 MHz band direct guadrature modulator for digital mobile communication systems. This Si-MMIC consists of pre-mixer for RF and IF local oscillator and 900 MHz band guadrature modulator which are packaged in 20 pin SSOP. The device has power save function and can operate 2.7 V to 3.6 V supply voltage. Therefore, it can contribute to make RF block small, high performance and low power consumption.
FEATURES
?Direct modulation range: 915 MHz to 960 MHz
?Pre-mixer for RF and IF local oscillator is incorporated.
?External local filter can be applied between pre-mixer output and modulator input port.
?Low operation current: I CC = 35 mA (typ.) @V CC = 3 V
?Equipped with power save function.
?20 pin SSOP suitable for high density surface mounting.
APPLICATIONS
?Digital cellular phones (PDC900 MHz etc.)
