Peak to Average Power Ratio: is a ratio between the peak signal power and average signal power level. Maximum input and output power: maximum input and output power handling must be considered during selection of an RF power amplifier. Exceeding input power level could damage an amplifier and it is critical if you are cascading more than one amplifier …
Ensuring proper biasing and supply of power to amplifiers in an RF signal chain can be a challenge, especially with drain voltages also used as the output port. There are numerous types of power solutions and topologies on the market. Which power solution you may need will depend on your application and system requirements.
Some radio amateurs, especially those who are new to the hobby, may not even know there are two main types of power supplies. They could be forgiven for that. When you need a power supply, you just jump online, pick out that one suits your needs and budget, and click. No one really thinks about what goes on in the guts of a power supply.
Today’s radio frequency (RF) systems are becoming more and more complex. This added complexity requires the best performance across all system metrics such as stringent link and noise budgets. Ensuring the proper design of the entire signal chain is critical. An often-overlooked section of this signal chain is DC power.
Ensuring the proper design of the entire signal chain is critical. An often-overlooked section of this signal chain is DC power. It plays an important role in the system, but it can also introduce unwanted effects. One important measurement for RF systems is phase noise, a metric that can be degraded depending upon the choice of power solution.
A linear power supply may be a good choice if you have a fixed station where space/weight is not a big concern or you want to reduce RF interference. linear vs. switching power supply Switching power supplies are a relative newcomer to ham radio.
The Yaesu power supply is rated at 23a. I would NEVER tax a power supply at 100%. Allowing for other 13.8v radios and accessories (present and future) on the table, buy a supply that loafs along at ~50%. At a minimum get a non-switching power supply such as the Astron RS-50M and be done with it.

A good three-stage battery charger for lead-acid batteries may cost more than a power supply. Many chargers make horrific RF noise, so you may not want to operate while …
The battery at best will be 13.3v or so vs a power supply set to 13.8. Not much when fully charged, but once I had it drop down to 12.1 or so because I didn''t get the snow wiped off early in the day. The charge controller below will go up to a little over 14v during high sun levels for …
A look at energy harvesting from RF signals and how it can be used to power a multitude of wireless and distributed sensors, radios, and IoT-connected devices.

Not much when fully charged, but once I had it drop down to 12.1 or so because I didn''t get the snow wiped off early in the day. The charge controller below will go up to a little over 14v during high sun levels for charging the battery, so this gives you a little ...
For example, a 12Ah battery should, in theory, supply 12Amps for 1 hour straight. It is generally less than that, depending on the battery type. Consider the "duty cycle" of your operations and mode. Assume 50% receive and 50% transmit time. For receive you will use 0.9A x …
