•
•
The KH600 is the first amplifier to combine differential input
and output with a bandwidth of DC-1GHz at 2Vpp. The
inputs and outputs are 100Ω differential (50Ω single ended).
The KH600 operates from ±5V supplies and offers a fixed
gain of 14dB (5V/V).

Functional Description
+Vs
The circuit is a differential amplifier with current output and
feedback. The simplified schematic is shown in Figure 1. The
output impedance is set by the value of the feedback resistors
(R3-R6) and the gain of the current mirrors. Amplifier gain is
set by R1 and R2. All of these resistors are internal due to the
high bandwidth of the amplifier.

Q1
The common mode output voltage (both outputs together) can
be varied by changing the voltages on +Vb1, +Vb2 and -Vb.
Making all three voltages more negative (for instance, +Vb’s
change from +5 to +3, and -Vb changes from -5 to -7) will
cause the output common mode level to become more positive.
The opposite conditions will cause the output common mode
level to become more negative. This can be very useful in driving
differential circuits which have an elevated DC common
mode input level. See Adjusting Common Mode Output
Offset Voltage section for more details.

The KH600 is a 1GHz differential input/output amplifier
constructed using Cadeka’s in-house thin film resistor/bipolar
transistor technology. A differential signal on the inputs of the
KH600 will generate a differential signal at the outputs. If a
single ended input signal is applied to IN1 and a fixed voltage
to IN2, the KH600 will produce both a differential and commonmode output signal. To achieve the maximum dynamic range,
center the inputs halfway between +Vs and -Vs.

• Trim the differential output offset voltage
• Adjust the common mode output offset voltage

If these adjustments are not required, short +Vb1 and +Vb2 to

data sheet, this configuration (+Vb1 = +Vb2 = +Vs = +5V and
-Vb = -Vs = -5V) is referred to as the Standard Operating
Condition. All of the plots in the Typical Performance section
and the specifications in the Electrical Characteristics table
utilize the basic circuit configuration shown in Figure 2,

Gain
Differential Gain for the KH600 is defined as (OUT1– OUT2)/
(IN1–IN2). Applying identical (same phase) signals to both
inputs and measuring one output will provide the Common
Mode Gain. Figure 4 shows the differential and common
mode gains of the KH600. Figure 5 illustrates the response
of the KH600 outputs when one input is driven and the other
is terminated into 50Ω.

The KH600 runs at “constant” power, which may be calculated
by (Total Is)(Vs – (-Vs)). Under standard operating conditions,
the power is 890mW. The power dissipated in the package is

changing -Vb.

Figure 8: ±Vs PSRR
Figure 9 shows the response of OUT1 and OUT2 when +Vb1
changes. The PSRR of the Vb pins is “bad”, which means
that they have a large effect on the response of the KH600
when their voltages are changed. This is the desired effect of
the bias voltage pins. As Figure 9 indicates, changing +Vb1
has a greater effect on OUT1 than it does on OUT2.
Changing +Vb1 has a direct effect on OUT1. Changing +Vb2
has a direct effect on OUT2. See the Trimming Differential

The KH600 is specifically designed for differential-todifferential operation. However, the KH600 can be used in a
single-to-differential configuration with some performance
degradation. The unused input should be terminated into 50Ω.
When driven single-ended, there will be a slight imbalance in
the differential output voltages, see Figure 5. This imbalance
is approximately 2.88dB. To compensate for this imbalance,
attenuate the higher gain output. (If the signal is applied to
IN1, attenuate OUT1.)

Adjusting Supply Current
The KH600 operates class A, so maximum output current is
directly proportional to supply current. Adjusting the voltages
on +Vb1 and +Vb2 in opposition to -Vb controls supply
current. The default supply current of the KH600 has been
optimized for best bandwidth and distortion performance. The
main reason for adjusting supply current is to either reduce
power or increase maximum output current. Adjusting the
supply current will not significantly improve bandwidth or
distortion and may actually degrade them.

Distortion (dB)
To adjust the supply current, apply voltages of equal magnitude,
but opposite polarity, to the bias voltage pins. For example,
setting +Vb1, +Vb2 to +5VDC and -Vb to -5VDC (as shown
in Figure 3) results in the standard supply current condition.
Setting +Vb1, +Vb2 to +5.5V and -Vb to -5.5V results in an
approximate 10% increase in supply current. Figure 10 shows
the how the total supply current of the KH600 is effected by
changes in the bias voltages (Vb = +Vb1 = +Vb2 = |-Vb|).

Trimming Differential Output Offset Voltage
Vary +Vb1 and +Vb2 to adjust differential offset voltage.
+Vb1 controls OUT1 and +Vb2 controls OUT2. The output
voltage moves in a direction opposite to the direction of the
bias voltage. Figure 15 shows the resulting voltage change at
OUT1 and OUT2 when the voltage on +Vb1 is changed.
Figure 16 shows the resulting voltage change at OUT1 and
OUT2 when the voltage on +Vb2 is changed. OUT1 and
OUT2 change at the same rate when -Vb is changed, as
shown in Figure 17. Therefore, changing the voltage on -Vb
has no effect on differential output offset voltage.
Adjusting Common Mode Output
Offset Voltage
Short +Vb1 to +Vb2 and vary +Vb and -Vb to adjust common
mode output offset voltage. The recommended values for
achieving a given output offset are shown in Figure 18. These
values were chosen to give the best distortion performance.
The exact values are not crucial.

Pay close attention to your peak-to-peak output voltage
requirement. As you change the common mode voltage, you
may need to increase or shift ±Vs in order to achieve your
output requirements. A 2V margin is recommended. For
example, if your output requirement is 5Vpp and you will be

changing the common mode from 1V to 3V set Vs = +7.5 and
-Vs to -3.5V. This example calls for a supply voltage of greater
than 10V. This will not effect supply current because as Figure 11
indicates, changing ±Vs has no effect on supply current.

Layout Considerations
General layout and supply bypassing play major roles in high
frequency performance. Cadeka has evaluation boards to use
as a guide for high frequency layout and as aid in device testing
and characterization. Follow the steps below as a basis for
high frequency layout:
• Include all recommended 6.8µF and 0.01µF
bypass capacitors
• Place the 6.8µF capacitors within 0.75 inches of
the power pin
• Place the 0.01µF capacitors within 0.1 inches of
the power pin
• Remove the ground plane under and around the part,
especially near the input and output pins to reduce
parasitic capacitance
• Minimize all trace lengths to reduce series inductances
• A 10pF to 50pF bypass capacitor can be used between
pins 5 and 6 and between pins 10 and 11 to reduce
crosstalk from the positive supply
Refer to the evaluation board layouts shown in Figure 22 for
more information.
