MIL-PRF-49164C(CR)
3.4.3 Dimensions. To ensure accurate interface with existing hardware, dimensions and
dimensional tolerances shall be in accordance with Drawing SM-D-773900 for maximum
overall height of components from the printed wiring board, dimensions of the printed wiring
board shall be in accordance with Drawing SM-D-773889 and pinouts to the connectors shall be
in accordance with Drawing SM-D-773899.
3.5 Performance characteristics.
3.5.1 Channel-to-channel tracking. The voltage gain of the postamplifier channels shall
track within ± 10 percent of the average gain at ambient temperature ranges of +55°C to +71°C
and 0°C to -54°C, and within ±5 percent over the range of 0°C to +55°C.
3.5.2 Gain tracking error. Channel-to-channel gain tracking shall not vary more than ±5
percent over the gain control range (30 dB minimum) at ambient temperature (+23, ±5°C). The
gain tracking error shall not vary more than ±5 percent over the temperature range of 0°C to
+55°C and shall not vary more than ±10 percent from +55°C to +71°C and from 0°C to -54°C.
3.5.3 Voltage gain. Voltage gain shall be a minimum of 18,000 volts per volt (V/V) in
high power mode (see 3.5.8).
3.5.4 Gain control. Gain control range shall be 0 to 30 dB minimum. Gain control range
is determined by controlling the positive and negative limits of the externally supplied gain
command voltages which determine the maximum and minimum gain, respectively.
3.5.5 Signal bandwidth. The upper 3 dB frequency shall be between 72 kHz and 172
kHz. Midband gain reference: 0 dB at 1 kHz in both high and low power modes (see 3.5.8).
3.5.6 Input impedance. Input impedance shall be 10,000, ± 2,500 ohms.
3.5.7 Output current. Output current capability shall be 10, ±3 milliamperes (mA) peak
into a 470 ohm resistive load.
3.5.8 Input power. Supply voltages and currents for low-power and high-power
applications are listed as follows:
Low-power mode
High-power mode
