The mixer used in this design is a general purpose up-/downconversion gilbert cell
mixer. An amplified and filtered RF signal enters the IC via the pins MI/MIX. Using an
external supplied local oscillator at LO/LOX a converted output signal is created at the
open collector output pins MO/MOX, which have to be connected to an external voltage
supply. The RF connections to the mixer inputs may be single ended or balanced,
capacitive or inductive coupled.
Voltage supply for the mixer has to be connected to the pins
V
S
and GND. To increase
the mixer current resistors need to be connected between the pins MI and GND, and
between the pins MIX and GND.
Differential signals and symmetrical circuits are used throughout the IC.
An internal bias driver generates supply voltage and temperature compensated
reference voltages.
All pins with the exception of GND are ESD protected.
