| VENUS-L CDMA/AMPS Dual Band RF Receiver Preliminary Information DS5082 Issue 2.1 J June 1999 Features q Selectable dual RF input ports for 900MHz AMPS and 1900MHz CDMA bands. q Power Management Control Ordering Iinformation VENUS-L/KG/QP1S VENUS-L/KG/QP1T Description VENUS-L is a dual integrated mixer circuit designed to meet the IS95 and J-STD-008 receive system specifications operating in the 900 MHz and 1900MHz bands. VENUS-L is part of a complete chipset solution for CDMA phones called the Planet chipset, and is built on a Mitel advanced bipolar process with FT's of 25GHz.

SPOT LO 2GHZ GND RF 900 GND CHIP ENABLE GND LO 1GHZ VCC AMPS IFB 8 9 AMPS IF QSOP16 Figure1 Pin Connections Circuit Description The RF section of VENUS-L contains all of the circuitry necessary to downconvert the RF signal from 900 MHz or 1900 MHz to an IF of 50-250 MHz, and to correctly interface with a suitable IF SAW filter. Two RF inputs are provided, one for the 1900MHz band and one for the 900 MHz band. The required input is activated by means of the `BAND 1900' pin. The input is a gm stage which will provide a characteristic impedance to correctly terminate the RF image-reject SAW filter. Two LO ports are provided, one for 1900MHz band and one for 900 MHz band, both with low noise buffer amplifiers. External matching components are required on the RF, LO and IF ports.
