C9 is inserted to ensure pin 6, Vref, remains at a.c. ground. 100 nF is recommended.

can also be set by directly driving Vref with a low impedance voltage source. (See Figure 4). It is
recommended that a small resistor be placed in series with the Vref pin. In this case:

Calculating Component Values For AC Transmission
There are five parameters a designer should know before starting the component calculations. These five
parameters are:
1) characteristic impedance of the line Z
o
2) network balance impedance Z
NB
3) value of the feed resistors (R1 and R2)
4) 2 W to 4 W transmit gain
5) 4 W to 2 W receive gain
The following example will outline a step by step procedure for calculating component values. Given:
Z
o
= 600
, Z
NB
= 600
, R1=R2= 220
Gain 2 - 4 = -1dB, Gain 4 - 2 = -1dB
Step 1: Gain Setting (R12, R13, R14, R15)
Gain 2 - 4 = 20 Log [ R13 / R12]
-1 dB =
20 Log [R13 / R12]
∴
R12 = 112.2k
, R13 = 100k
.
Gain 4 - 2 = 20 Log [0.891 * [R14 / R15)]
-1 dB = 20 Log [0.891 * [R14 / R15)]
∴
R14 = 100k
, R15 = 100k
.
