Abstract
In case of UHF Band Transceiver for Army Aircraft, it shall follow MIL-STD-461F Figure CE101-4 most key design points for this equipment were to minize the current consumption and frequency interference since it will be integrated on aircraft. However, after design, abnomal signal(over 100 dBuA) was occured from 30 Hz to 1 kHz on CE101 test. Occured abnomal signal was measured as 50 Hz signal which was tansceiver $\small{T_{DD}}$ signal with the output power of 10 W and 20 ms periods. To meet the specification, current variation needed to be minized. Thus, $\small{I_{dq}}$ and $\small{I_d}$ of power amplifier were modified almost equally through test result and finally, the equipment was designed and developed with no difference of current consumption and frequency interference from the previous design goal.
