1. GENERAL INFORMATION
2. The HP Models 8447D, 8447E and 8447F are
general purpose, wideband amplifiers. Each instru-
ment consists of a power supply and one or two
thin film, hybrid, integrated circuit amplifiers. The
thin film amplifiers are hermetically sealed and
feature low noise, low distortion, flat frequency
response, and long term stability and reliability.
3. The HP Model 8447D Amplifier is a pre-
amplifier that provides 26 dB of gain to signals
from 100 kHz to 1.3 GHz. It can be used to
increase the sensitivity of any lab, shop or field
device operating within its frequency range.
Page 1
4. The HP Model 8447E Amplifier is a power
amplifier that provides 22 dB of gain to signals
from 100 kHz to 1.3 GHz. It can be used to
increase the output power of signal generators,
sweepers and similar devices operating within its
frequency range.
5. The HP Model 8447F Amplifier contains a
preamplifier and a power amplifier — the same
thin film amplifiers used in the HP 8447D and
HP 8447E. The input and output ports of both
amplifiers are available on the front panel; they
can be used separately or cascaded to provide
48 dB of gain.

Gain Compression
Description:
Amplifier gain is measured at the maximum and minimum points of its frequency response (see
Figures 1 and 2). The difference between highest measured gain and lowest measured gain should be
less than 3 dB (gain flatness). Half of the sum of highest gain and lowest gain is measured mean gain
and should be within 1.5 dB of specified gain. Compression is checked by measuring gain at the
specified 1 dB compression point and comparing it to gain measured below compression.

PERFORMANCE TESTS
55. Gain Flatness, Mean Gain, and Gain Compression (Cont.)
Procedure:
1. To measure gain flatness and mean gain, connect the equipment as shown in Figure 3. Set the
sweep oscillator for a 1.3 GHz, leveled, CW signal; set the signal level for —10 dBm out of the 10 dB
attenuator (read on the power meter).
2. Disconnect the power meter from the sweep oscillator and 10 dB attenuator. Connect the sweep
oscillator, through the 10 dB and 20 dB attenuators, to amplifier INPUT; connect the power meter to
amplifier OUTPUT. Note the power meter reading. Use this reading to calculate amplifier gain.
EXAMPLE:
—7 dBm (read in step 2) minus —10 dBm (set in step 1) plus 20 dB (read from attenuator) = 23 dB (gain)
Gain at 1300 MHz: dB
NOTE
Use attenuation printed on 20 dB attenuator; this may vary slightly, depending
upon frequency.
3. Tune the sweep oscillator for a maximum indication on the power meter at 1150 +100 MHz.
Disconnect the oscillator and the power meter from the amplifier. Connect the power meter, through
the 10 dB attenuator, to the oscillator. Set the oscillator signal level for —10 dBm out of the attenuator.
4. Disconnect the power meter from the sweep oscillator and 10 dB attenuator. Connect the oscil-
lator, through the 10 dB and 20 dB attenuators, to amplifier INPUT; connect the power meter to
amplifier OUTPUT, Calculate and record amplifier gain (as performed in step 2).
Gain at 1150 MHz: dB
5. Measure, calculate and record amplifier gain at the following frequencies; use the procedures
outline in steps 3 and 4.
Frequency Gain
800 +200 MHz (tune for minimum): dB
350 +100 MHz (tune for maximum): dB
6. Disconnect the sweep oscillator and the power meter from the amplifier. Connect the equipment
as shown in Figure 4. Set the generator/sweeper for a 10 MHz, CW signal; set the signal level for
—40 dB (read on the voltmeter).
7. Disconnect the voltmeter from the generator/sweeper. Connect the generator/sweeper to amplifier
INPUT; connect the voltmeter, with the 50 ohm termination, to amplifier OUTPUT. Note the volt-
meter reading. Use this reading to calculate amplifier gain.
EXAMPLE:
—18.5 dB (read in step 7) minus —40 dB (set in step 6) = 21.5 dB (gain)

9. Select the highest and lowest gains from steps 2, 4, 5, 7, and 8. Subtract the lowest gain from the
highest gain; the result is gain flatness and should be less than 3 dB.
EXAMPLE:
23 dB (highest gain) minus 21.5 dB (lowest gain) = 1.5 dB (gain flatness)
Gain Flatness: 3 dB
10. Add the highest and lowest gains together and divide by 2; the result is measured mean gain.

Noise Figure:
Description:
< 8.5 dB (for 8447D PRE AMP and 8447F PRE AMP).
Noise figure is checked at 100 MHz by inserting a known amount of excess noise into the amplifier
under test; the known noise is then compared to the amplifier’s noise level with a noise figure meter.
Noise is checked at 1200 MHz using a 1300 MHz signal source and a mixer to convert the noise to
100 MHz; then it is measured with the meter.

REQUIRED FOR TROUBLESHOOTING
66. Test Equipment and accessories required to
troubleshoot the amplifier are shown in Table 2.
Test Instruments other than those listed may be
used provided their specifications meet or exceed
those listed in Table 2.
67. GENERAL SERVICE INFORMATION
68. The part reference designator is the assembly
designator plus the part designator. (Ex-
ample: A1R9 is R9 on the Al Power Supply
Assembly.) Refer to the parts list on Table 4, 5 or
6 for specific component description for ordering
parts.
Page 27
69. TROUBLESHOOTING PROCEDURE
70. First check the input and output cables.
Isolate trouble to the amplifier(s) or power supply
by checking the +20 volts at XAl—14 after
removing the red wire from C2. If the voltage is
present, replace the amplifier (re-attach the red
wire to C2). If voltage is not present or incorrect,
check the power supply. The voltages shown are
typical with the amplifier(s) disconnected from the
power supply.
