Abstract:

The report describes the test and evaluation of a prototype very high frequency VHF low-intermodulation amplifier that was designed as a frequency-independent interference rejection circuit for the T-1108GRT-21 airground communication transmitter. Test results showed the amplifier could reduce T-1108GRT-21 transmitter third-order intermodulation products at least 48 dB when aligned for a single interfering frequency condition, but the amplifier did not achieve the desired 15-dB intermodulation reduction when aligned for broadband interference cancellation across the 118-136 MHz VHF airground communication frequency band.
