Abstract
This paper is a study on the high power amplifier to fulfill standards of the MOPS. VDR's frequency band is 117.975~137MHz, and CSMA(Carrier Sense Multiple Access), D8PSK(Differential Eight Phase Shift Keyed), 25KHz's channel bandwidth use. It also stated in DO-281A MOPS output power, symbol constellation error, spurious emissions, adjacent channel power must be met. We designed and measured the performance. The 38dB of the IM3 satisfies the MOPS standard.
