PIN CONFIGURATION (TOP VIEW)

PLL and Modulator.

Using Bi-CMOS technology, it contains dual PLL

(1.8GHz, 550MHz), a mixer for 2nd IF, transistor

for VCO , modulator and Up-convertor on chip.

FEATURES

• Built-in 2nd mixer and RSSI

• Vcc=2.7 to 3.6V

• Icc= TYP.41mA (TX.), TYP.23mA (RX.)

• Built-in high accuracy phase shifter (CR type)

• Large Output (-13dBm type)

• Attenuator for Gain Control

• Gain characteristics with temperature dependent

• Built-in transistor and Buffer for 2nd Local VCO

• Built-in Buffer for 1.6GHz VCO

• Small Package (48pin QFP, lead pitch 0.5mm)
