This chapter presents a transceiver sensitivity modeling and link characterization over-the-air (OTA) for K/Ka-band frequency for next-generation 5G and low earth orbit (LEO) communication applications. The transceiver system is simulated using estimated link budget parameters. The simulated transceiver includes a DQPSK modulator, a power amplifier, a low noise amplifier, and mixers optimized to meet industry specifications. The transmitter front-end shows a 24.6 dBm output power with an input transmission power of 0 dBm. The receiver simulation shows a gain of 48 dBm and an intermediate frequency output power of 35.8 dBm. The simulated sensitivity of the receiver spans from -115 dBm to -110 dBm, indicating good coverage over the channel bandwidth.
