Circuit Description
MIXER
The mixer used in this design is a general purpose up-/down conversion gilbert cell
mixer. Via the pins MI/MIX the RF enters the IC. Using an external supplied local
oscillator at LO/LOX a converted output signal is created at the open collector output
pins MO/MOX. The open collector pins need to be connected to an external voltage
supply. The RF connection to the mixer inputs can be single ended on balanced,
capacitive or inductive. To improve the mixer performance external resistors at MI/MIX
make it possible to adjust the mixer current. Voltage supply for the mixer has to be
connected to the pin VCC and to GND2.
AMPLIFIER
The amplifier may be used as a low noise amplifier LNA or as a driver. At pin AI the RF
signal enters the IC, at the open collector output AO, which need to be connected to
supply voltage, the amplified signal is external available for further use. Matching
networks at in-/and output can be used for improving the gain and the noise
performance. To reduce the series feedback of the emitter line the amplifier is connected
to ground via three GND1 pins. At AREF a internal supplied reference voltage is
available for the DC biasing of AI. This dc output should be implemented in an input
matching network. The voltage supply for the amplifier is also VCC. The dc-level at the
pin GC allows to adjust the amplifier current.
Lower current is recommended for using the amplifier as an LNA, high current for using
it as a driver.
COMMON
Differential signals and symmetrical circuits are used throughout the mixer part of the IC.
An internal bias driver generates supply voltage and temperature compensated
reference voltages. The STB pin allows the mixer and bandgap part of the IC to be
switched in a low power mode.
All pins with the exception of GND1,2 and AI/AO are ESD protected.
