Aerospace and defense communications RF block diagram

Description
Most modern defense communications are now based on SDR (Software Defined Radio). This advancement has led to more efficient communications over larger operating bandwidths and greatly improved inter-operability between different services. The advent of SDR has posed a significant challenge for power amplifiers. The broadband, multi-mode SDR is still somewhat limited by the bandwidth of the amplifier.
NXP’s LDMOS is used today in the world’s premier radios due to its excellent operating bandwidth and extremely rugged design – which can survive harsh mismatches in extreme circumstances. As with AESA radar, our SiGe:C process plays a crucial role in offering integration to radio designers for RF signal processing and consistent RF performance over temperature and processing.
