MIL-DTL-22442/1C(AS)
d. Transformer dc resistance. The primary and secondary dc resistance's shall be as
specified.
e. Transformer output. The transformer output shall be measured to ensure compliance
with Requirement 9 by measuring the primary and secondary voltages when terminated
with the proper resistive load.
11. Audio amplifier shall have the following characteristics:
Amplifiers M22442/l-2 and M22442/l-5
a. The frequency response of the amplifiers shall be within the limits of figure 5 from
300 to 6000 Hz.
b. The nominal load impedance shall be 100 ohms.
12. Audio amplifiers. Audio amplifiers furnished as part of a cable assembly under this
specification shall, as a minimum, meet the following requirements under ambient and during
environmental conditions. The output of the amplifier shall be terminated with a non-inductive,
high precision (±1%) resistive load equivalent to the nominal load impedance (l00 ohms unless
specified), and the nominal input voltage shall be 250 (±10) microvolts.
13. Amplifier frequency response (voltage gain). The gain of the amplifier under load shall be
as specified over the frequency range of 300 to 6000 Hz, except that when operated between -
350C and -540C, the output may be down an additional 6 dB from the gain under standard
conditions.
* 14. Amplifier input power. The input power to the amplifier shall be 27.5 (±.5) volts dc and
shall be provided across the output terminals of the amplifier. The amplifier shall require no
more than 18 milliamps dc input to provide the specified gain over the range of 300 to 6000 Hz.
15. Amplifier distortion. Unless otherwise specified, the total harmonic distortion (THD) of the
amplifier shall not exceed 15% between 300 to 1000 Hz and 5.0 % over the frequency range of
1000 to 3000 Hz with any supply voltage from 22 to 30 volts dc. Under low voltage conditions, 10
to 22 volts dc, the amplifier distortion shall not exceed 40% between 1000 to 3000 Hz.
16. Amplifier linearity. The output voltage shall be a linear function of the input voltage
within ±2 dB over the input voltage range of 50 to 500 microvolts.
17. Amplifier stability. No damage shall result from amplifier operation with the output
terminated in an open circuit, and the amplifier shall resume normal operation once the nominal
load impedance is restored. The amplifier shall be stable and shall show no evidence of
regeneration or oscillation when operated from a power source which may provide any voltage
from 10 to 30 volts, with input and output circuits terminated in the required impedance. There
shall be no output when the microphone keying switch is released.
