As a practical design example, design the interface for
the following set of requirements per TA-909.
RX = –4 dB
TX = –2 dB
ZT = 600
—> (R
1
= 600; R
2
= 0; C =
∞
)
Hy = 600
Thus:
R
1
′
= 600
R
2
′
= 0
C

=
∞
Calculate the gain constants:
K
O

RX/20

–4/20
= 0.631
K
TX
=

TX/20
= 1 x 10
–2/20
= 0.794
Calculate individual components:
R
RV1

= 95.1 k
Using a standard value component:
R
RV1
= 95.3 k
R
RV2
=
= 0
C
R

Choose R
GX1
= 82.5 k
R
T1
= 21.4 k
Using a standard value component:
R
T1
= 21.5 k
C
T

C
T

R
T2

R
GX

TX
(R
GX1
+ R
T1
)
R
GX
= 2 x 0.794 (82.5 + 21.5) = 165.2 k
Using a standard value component:
R
GX
= 165 k
R
HB
=
R
HB
=
Using a standard value R
HB
= 332 k
.
Therefore, for this design example, use the following
values in the circuit shown in Figure 11.
R
T1
= 21.5 k
R
T2
= 0
R
GX
= 165 k
R
GX1
= 82.5 k
R
RV1
= 95.3 k
R
RV2
= 0
R
HB1
= 332 k
C
T

C
R

Figure 14 is the application circuit with the above
values.
