Description

VENUS-L is a dual integrated mixer circuit designed to meet the IS95 and J-STD-008 receive system specifica- tions 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. Figure 2. Block diagram

VENUS-L Preliminary Information PIN 1 REF. SPOT Figure1 Pin Connections QSOP16 CDMA IF CDMA IFB VCC LO 2GHZ GND RF 900 GND CHIP ENABLE BAND 1900 GND RF 1900 GND LO 1GHZ VCC AMPS IFB AMPS IF 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.
