NEjSA602
Double-Balanced Mixer and
Oscillator
Product Specification
DESCRIPTION
The SA/NE602 is a low-power VHF
monolithic double-balanced mixer with
input amplifier, on-board oscillator, and
voltage regulator. It is intended for high
performance, low power communication
systems. The guaranteed parameters of
the SA602 make this device particularly
well suited for cellular radio applications.
The mixer is a "Gilbert cell" multiplier
configuration which typically provides
18dB of gain at 45MHz. The oscillator
will operate to 200M Hz. It can be config-
ured as a crystal oscillator, a tuned tank
oscillator, or a buffer for an external L.O.
The noise figure at 45MHz is typically
less than 5dB. The gain, intercept per-
formance, low-power and noise charac-
teristics make the SAlNE602 a superior
choice for high-performance battery op-
erated equipment. It is available in an 8-
lead dual in-line plastic package and an
8-lead SO (surface-mount miniature
package).
FEATURES
• Low current consumption: 2.4mA
typical
• Excellent noise figure: < 5.0dB
typical at 45MHz

DESCRIPTION OF OPERATION
0.5 to 1.3~H
I122PF
~
The NE/SA602 is a Gilbert cell, an oscillatorl
buffer, and a temperature compensated bias
44.545MHz THIRD OVERTONE CRYSTAL
network as shown in the equivalent circuit.
Vee The Gilbert cell is a differential amplifier (Pins
1 and 2) which drives a balanced switching
cell. The differential input stage provides gain
and determines the noise figure and signal
150pF
handling performance of the system.
~602 1.5 to
44.2p
The NE/SA602 is designed for optimum low
power performance. When used with the
SA604 as a 45MHz cellular radio 2nd IF and
120pF
demodulator, the SA602 is capable of receiv-
ing -119dBm signals with a 12dB SIN ratio.
Third-order intercept is typically -15dBm
(that's approximately +5dBm output intercept
because of the RF gain). The system design-
er must be cognizant of this large signal
limitation. When designing LANs or other
closed systems where transmission levels are
high, and small-signal or signal-to-noise
issues not critical, the input to the NE602
Figure 1. Test Configuration
should be appropriately scaled.
