Link coupling is used to transfer energy between two r-f circuits which for whatever reason cannot be located near to each other. The method used in link coupling is a wire loop which stretches between the two stages, terminating at each end in a coil of few turns. At the output of the first stage, this wire loop will act as a step-down transformer, and at the input of the next stage it will act as a step-up transformer. To work in this manner the loop terminations must be positioned next to the inductor of the r-f tank circuit.

RF power amplifiers
Do you mean with opamp circuits or tuned RF/IF amplifiers? In both cases several stages can be used to increase the gain. With opamp circuits though getting both wide bandwidth and high gain at the same time is difficult. With tuned RF/IF amplifiers two things can be done to get wide bandwidth: 1) reduce the Q of the tuned coupling transformers connecting the stages and 2) stagger the tuning of the tuned coupling transformers connecting the stages so that some are detuned high while others are detuned low.

An rf link transmitter is used to connect different repeaters together in a wireless network. A repeater is used to strengthen a wireless signal and provide better coverage.
An RF (radio frequency) subsystem is a segment of an electronic system that is dedicated to handling radio frequency signals. It typically includes components such as RF amplifiers, filters, and mixers that are used to process and manipulate RF signals within a larger electronic system. RF subsystems are commonly used in communication devices, radar systems, and other applications that involve transmitting or receiving radio frequency signals.
Top coupling is a method of connecting the input and output of an RF amplifier circuit using capacitors on the top side of the circuit. It allows for direct coupling between stages without the need for additional components. Top coupling helps maintain the impedance matching and overall performance of the amplifier.
RF link refers to a wireless communication connection between devices using radio frequency signals. It allows devices to communicate and exchange data without the need for physical cables. RF links are commonly used in various applications such as wireless networks, remote controls, and IoT devices.
The main hazard is RF burns from improperly placed mono polar return pad. Another hazard is capacitively coupling of pieces of metal used in the procedure, for example knives, retractors, haemostats.
