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.
