The maximum frequency one can allocate to a Transceiver (TRX) during RF hopping depends on the specific communication standards and regulations in place, such as those set by the FCC or other relevant authorities. Generally, frequency hopping spread spectrum (FHSS) systems must adhere to certain bandwidth and frequency separation requirements to avoid interference and meet legal specifications. In practice, the maximum frequency allocation can vary widely based on the system design and intended application, but it is typically constrained by the overall bandwidth available within a given frequency band.
A; PWM is extensively used in PWM power supply whereby a fix frequency is setup but the duty cycle change to transfer power. Actually the maximum power is transferred during the rise and fall of the square wave

The transformer used to combine audio frequency signals with high-frequency carrier signals in a radio transmitter is called a modulation transformer. This type of transformer effectively couples the low-frequency audio signals to the high-frequency RF (radio frequency) carrier, allowing for efficient transmission of the combined signals. It ensures minimal loss and maintains the integrity of both frequency components during the modulation process.
Alternating current varies in magnitude, and reverses direction every half-cycle. When the current is drifting in one direction we allocate it a 'positive' direction; when it reverses direction we allocate it a 'negative' direction. So the positive half-cycle refers to its variation in current during its forward or positive direction and the negative half-cycle refers to its variation in current during its reverse or negative direction.
Antenna hopping is a feature in which the Tx/Rx is passed through all the available antenna paths in a sector. No frequency is changed during antenna hopping. This helps improve performance by providing spatial diversity.
Frequency Hopping is an old technique introduced firstly in military transmission system to ensure the secrecy of communications and combat jamming. Frequency Hopping is mechanism in which the system changes the frequency (uplink and downlink) during transmission at regular intervals. It allows the RF channel used for signaling channel (SDCCH) timeslot or traffic channel (TCH) timeslots, to change frequency every TDMA frame (4.615 ms). The frequency is changed on a per burst basis, which means that all the bits in a burst are transmitted in the same frequency.
Island hopping is moving around from island to island. For example, The United States military practiced island-hopping during WWII in the war in the Pacific.
Dry hopping involves adding hops to the beer during or after fermentation, while wet hopping involves using fresh, undried hops. Dry hopping adds aroma and flavor without much bitterness, while wet hopping can provide a more delicate and fresh hop character.
One Allied victory during the Island Hopping battles of the Pacific Ocean was gaining control of the Solomon Islands.
In antenna hopping the transmit antenna is changed during the interleaving period resulting in an increased channel diversity which can be converted into a performance gain through the channel coding.

he invented "island hopping" during ww2, he also defeated the Japanese
