1.6 Circuit Description

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 VS 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.
