Note 9 – Coupling and Bypass Capacitors Cl and C2

Note 12 – Signal Port Stability

Capacitors Cl and C2 (Figure 5) should be selected for a re-

actance of less than 5.0 ohms at the carrier frequency.

Note 10 – Output Signal, V.

The output signal is taken from pins 6 and 9, either balanced

or single-ended. Figure 12 shows the output levels of each of the

two output sidebands resulting from variations in both the car-

rier and modulating

signal inputs with a single-ended

output

connection.

Under certain values of driving source impedance, oscillation

may occur. I n this event, an RC suppression network should be

connected directlv to each input using short leads. This will reduce

the 0—of the source-tuned circuits that muse the oscillation
